The HI08 port supports a non-multiplexed or a multiplexed bus, single or double Data Strobe (DS), and single or double Host Request (HR) configurations. Since each of these modes is configured independently, any combination of these modes is possible. These HI08 signals can also be configured alternatively as GPIO signals (PB[0-15]). Signals with dual designations (for example, HAS/HAS) have configurable polarity. The ESSI0, ESSI1, and SCI signals are multiplexed with the Port C GPIO signals (PC[0-5]), Port D GPIO signals (PD[0-5]), and Port E GPIO signals (PE[0-2]), respectively. TIO[0-2] can be configured as GPIO signals. Ground connections shown in this figure are for the TQFP package. In the MAP-BGA package, in addition to the GNDP and GNDP1 connections, there are 64 GND connections to a common internal package ground plane.

Address Attribute--When defined as AA, these signals can be used as chip selects or additional address lines. The default use defines a priority scheme under which only one AA signal can be asserted at a time. Setting the AA priority disable (APD) bit (Bit 14) of the Operating Mode Register, the priority mechanism is disabled and the lines can be used together as four external lines that can be decoded externally into 16 chip select signals. Row Address Strobe--When defined as RAS, these signals can be used as RAS for DRAM interface. These signals are tri-statable outputs with programmable polarity.
RAS[0-3] RD
Output Output Tri-stated
Read Enable--When the DSP is the bus master, RD is an active-low output that is asserted to read external memory on the data bus (D[0-23]). Otherwise, RD is tristated. Write Enable--When the DSP is the bus master, WR is an active-low output that is asserted to write external memory on the data bus (D[0-23]). Otherwise, the signals are tri-stated. Transfer Acknowledge--If the DSP56303 is the bus master and there is no external bus activity, or the DSP56303 is not the bus master, the TA input is ignored. The TA input is a data transfer acknowledge (DTACK) function that can extend an external bus cycle indefinitely. Any number of wait states (1, 2. . .infinity) can be added to the wait states inserted by the bus control register (BCR) by keeping TA deasserted. In typical operation, TA is deasserted at the start of a bus cycle, is asserted to enable completion of the bus cycle, and is deasserted before the next bus cycle. The current bus cycle completes one clock period after TA is asserted synchronous to CLKOUT. The number of wait states is determined by the TA input or by the BCR, whichever is longer. The BCR can be used to set the minimum number of wait states in external bus cycles. To use the TA functionality, the BCR must be programmed to at least one wait state. A zero wait state access cannot be extended by TA deassertion; otherwise, improper operation may result. TA can operate synchronously or asynchronously depending on the setting of the TAS bit in the Operating Mode Register. TA functionality cannot be used during DRAM type accesses; otherwise improper operation may result.

BR
Output
Reset: Output (deasserted) State during Stop/Wait depends on BRH bit setting: * BRH = 0: Output, deasserted * BRH = 1: Maintains last state (that is, if asserted, remains asserted)
Bus Request--Asserted when the DSP requests bus mastership. BR is deasserted when the DSP no longer needs the bus. BR may be asserted or deasserted independently of whether the DSP56303 is a bus master or a bus slave. Bus "parking" allows BR to be deasserted even though the DSP56303 is the bus master. (See the description of bus "parking" in the BB signal description.) The bus request hold (BRH) bit in the BCR allows BR to be asserted under software control even though the DSP does not need the bus. BR is typically sent to an external bus arbitrator that controls the priority, parking, and tenure of each master on the same external bus. BR is affected only by DSP requests for the external bus, never for the internal bus. During hardware reset, BR is deasserted and the arbitration is reset to the bus slave state.

BG
External Bus Control Signals (Continued)
Signal Description
Bus Grant--Asserted by an external bus arbitration circuit when the DSP56303 becomes the next bus master. When BG is asserted, the DSP56303 must wait until BB is deasserted before taking bus mastership. When BG is deasserted, bus mastership is typically given up at the end of the current bus cycle. This may occur in the middle of an instruction that requires more than one external bus cycle for execution. The default operation of this bit requires a setup and hold time as specified in Table 214. An alternate mode can be invoked: set the asynchronous bus arbitration enable (ABE) bit (Bit 13) in the Operating Mode Register. When this bit is set, BG and BB are synchronized internally. This eliminates the respective setup and hold time requirements but adds a required delay between the deassertion of an initial BG input and the assertion of a subsequent BG input.

Bus Busy--Indicates that the bus is active. Only after BB is deasserted can the pending bus master become the bus master (and then assert the signal again). The bus master may keep BB asserted after ceasing bus activity regardless of whether BR is asserted or deasserted. Called "bus parking," this allows the current bus master to reuse the bus without rearbitration until another device requires the bus. BB is deasserted by an "active pull-up" method (that is, BB is driven high and then released and held high by an external pull-up resistor). The default operation of this signal requires a setup and hold time as specified in Table 2-14. An alternative mode can be invoked by setting the ABE bit (Bit 13) in the Operating Mode Register. When this bit is set, BG and BB are synchronized internally. See BG for additional information. Note: BB requires an external pull-up resistor.

Tri-stated
Column Address Strobe--When the DSP is the bus master, CAS is an active-low output used by DRAM to strobe the column address. Otherwise, if the Bus Mastership Enable (BME) bit in the DRAM control register is cleared, the signal is tri-stated. Bus Clock When the DSP is the bus master, BCLK is active when the Operating Mode Register Address Trace Enable bit is set. When BCLK is active and synchronized to CLKOUT by the internal PLL, BCLK precedes CLKOUT by one-fourth of a clock cycle. Bus Clock Not When the DSP is the bus master, BCLK is the inverse of the BCLK signal. Otherwise, the signal is tri-stated.

The interrupt and mode control signals select the chip operating mode as it comes out of hardware reset. After RESET is deasserted, these inputs are hardware interrupt request lines.

Signal Name
RESET
Interrupt and Mode Control
Signal Description
Reset--Places the chip in the Reset state and resets the internal phase generator. The Schmitt-trigger input allows a slowly rising input (such as a capacitor charging) to reset the chip reliably. When the RESET signal is deasserted, the initial chip operating mode is latched from the MODA, MODB, MODC, and MODD inputs. The RESET signal must be asserted after powerup. Mode Select A--MODA, MODB, MODC, and MODD select one of 16 initial chip operating modes, latched into the Operating Mode Register when the RESET signal is deasserted. External Interrupt Request A--After reset, this input becomes a levelsensitive or negative-edge-triggered, maskable interrupt request input during normal instruction processing. If the processor is in the STOP or WAIT standby state and IRQA is asserted, the processor exits the STOP or WAIT state.

The HI08 provides a fast, 8-bit, parallel data port that connects directly to the host bus. The HI08 supports a variety of standard buses and connects directly to a number of industry-standard microcomputers, microprocessors, DSPs, and DMA hardware.
1.7.1
Host Port Usage Considerations
Careful synchronization is required when the system reads multiple-bit registers that are written by another asynchronous system. This is a common problem when two asynchronous systems are connected (as they are in the Host port). The considerations for proper operation are discussed in Table 1-10.

Host Port Usage Considerations
Description
When reading the receive byte registers, Receive register High (RXH), Receive register Middle (RXM), or Receive register Low (RXL), the host interface programmer should use interrupts or poll the Receive register Data Full (RXDF) flag that indicates data is available. This assures that the data in the receive byte registers is valid. The host interface programmer should not write to the transmit byte registers, Transmit register High (TXH), Transmit register Middle (TXM), or Transmit register Low (TXL), unless the Transmit register Data Empty (TXDE) bit is set indicating that the transmit byte registers are empty. This guarantees that the transmit byte registers transfer valid data to the Host Receive (HRX) register. The host interface programmer must change the Host Vector (HV) register only when the Host Command bit (HC) is clear. This practice guarantees that the DSP interrupt control logic receives a stable vector.

The DSP56300 family and in particular the DSP56303 support circuit-board test strategies based on the IEEE(R) Std. 1149.1TM test access port and boundary scan architecture, the industry standard developed under the sponsorship of the Test Technology Committee of IEEE and the JTAG. The OnCE module provides a means to interface nonintrusively with the DSP56300 core and its peripherals so that you can examine registers, memory, or on-chip peripherals. Functions of the OnCE module are provided through the JTAG TAP signals. For programming models, see the chapter on debugging support in the DSP56300 Family Manual.

Signal Description
Test Clock--A test clock input signal to synchronize the JTAG test logic. Test Data Input--A test data serial input signal for test instructions and data. TDI is sampled on the rising edge of TCK and has an internal pull-up resistor. Test Data Output--A test data serial output signal for test instructions and data. TDO is actively driven in the shift-IR and shift-DR controller states. TDO changes on the falling edge of TCK. Test Mode Select--Sequences the test controller's state machine. TMS is sampled on the rising edge of TCK and has an internal pull-up resistor. Test Reset--Initializes the test controller asynchronously. TRST has an internal pull-up resistor. TRST must be asserted after powerup. Debug Event--As an input, initiates Debug mode from an external command controller, and, as an open-drain output, acknowledges that the chip has entered Debug mode. As an input, DE causes the DSP56300 core to finish executing the current instruction, save the instruction pipeline information, enter Debug mode, and wait for commands to be entered from the debug serial input line. This signal is asserted as an output for three clock cycles when the chip enters Debug mode as a result of a debug request or as a result of meeting a breakpoint condition. The DE has an internal pull-up resistor. This signal is not a standard part of the JTAG TAP controller. The signal connects directly to the OnCE module to initiate debug mode directly or to provide a direct external indication that the chip has entered Debug mode. All other interface with the OnCE module must occur through the JTAG port.

Specifications
2.1 Maximum Ratings
CAUTION
This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, normal precautions should be taken to avoid exceeding maximum voltage ratings. Reliability is enhanced if unused inputs are tied to an appropriate logic voltage level (for example, either GND or VCC).
2
The DSP56303 is fabricated in high-density CMOS with transistor-transistor logic (TTL) compatible inputs and outputs.
In the calculation of timing requirements, adding a maximum value of one specification to a minimum value of another specification does not yield a reasonable sum. A maximum specification is calculated using a worst case variation of process parameter values in one direction. The minimum specification is calculated using the worst case for the same parameters in the opposite direction. Therefore, a "maximum" value for a specification never occurs in the same device that has a "minimum" value for another specification; adding a maximum to a minimum represents a condition that can never exist.

Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond the maximum rating may affect device reliability or cause permanent damage to the device.

Refers to MODA/IRQA, MODB/IRQB, MODC/IRQC, and MODD/IRQD pins. Section 4.3 provides a formula to compute the estimated current requirements in Normal mode. In order to obtain these results, all inputs must be terminated (that is, not allowed to float). Measurements are based on synthetic intensive DSP benchmarks (see Appendix A). The power consumption numbers in this specification are 90 percent of the measured results of this benchmark. This reflects typical DSP applications. Typical internal supply current is measured with VCC = 3.3 V at TJ = 100C. In order to obtain these results, all inputs must be terminated (that is, not allowed to float). In order to obtain these results, all inputs that are not disconnected at Stop mode must be terminated (that is, not allowed to float). PLL and XTAL signals are disabled during Stop state. Periodically sampled and not 100 percent tested. V CC = 3.3 V 0.3 V; TJ = -40C to +100 C, CL = 50 pF This characteristic does not apply to XTAL and PCAP. Driving EXTAL to the low VIHX or the high VILX value may cause additional power consumption (DC current). To minimize power consumption, the minimum VIHX should be no lower than 0.9 x VCC and the maximum VILX should be no higher than 0.1 x VCC .
2.5 AC Electrical Characteristics
The timing waveforms shown in the AC electrical characteristics section are tested with a VIL maximum of 0.3 V and a VIH minimum of 2.4 V for all pins except EXTAL, which is tested using the input levels shown in Note 6 of the previous table. AC timing specifications, which are referenced to a device input signal, are measured in production with respect to the 50 percent point of the respective input signal transition. DSP56303 output levels are measured with the production test machine VOL and VOH reference levels set at 0.4 V and 2.4 V, respectively. Note: Although the minimum value for the frequency of EXTAL is 0 MHz, the device AC test conditions are 15 MHz and rated speed.

External Clock Operation
The DSP56303 system clock is derived from the on-chip oscillator or is externally supplied. To use the on-chip oscillator, connect a crystal and associated resistor/capacitor components to EXTAL and XTAL; examples are shown in Figure 2-1.

The maximum value for PLL enabled is given for minimum VCO frequency and maximum DF. The skew is not guaranteed for any other MF value. The indicated duty cycle is for the specified maximum frequency for which a part is rated. The minimum clock high or low time required for correction operation, however, remains the same at lower operating frequencies; therefore, when a lower clock frequency is used, the signal symmetry may vary from the specified duty cycle as long as the minimum high time and low time requirements are met.

When fast interrupts are used and IRQA, IRQB, IRQC, and IRQD are defined as level-sensitive, timings 19 through 21 apply to prevent multiple interrupt service. To avoid these timing restrictions, the deasserted Edge-triggered mode is recommended when fast interrupts are used. Long interrupts are recommended for Level-sensitive mode. This timing depends on several settings: * For PLL disable, using internal oscillator (PLL Control Register (PCTL) Bit 16 = 0) and oscillator disabled during Stop (PCTL Bit 17 = 0), a stabilization delay is required to assure that the oscillator is stable before programs are executed. Resetting the Stop delay (Operating Mode Register Bit 6 = 0) provides the proper delay. While Operating Mode Register Bit 6 = 1 can be set, it is not recommended, and these specifications do not guarantee timings for that case. * For PLL disable, using internal oscillator (PCTL Bit 16 = 0) and oscillator enabled during Stop (PCTL Bit 17=1), no stabilization delay is required and recovery is minimal (Operating Mode Register Bit 6 setting is ignored). * For PLL disable, using external clock (PCTL Bit 16 = 1), no stabilization delay is required and recovery time is defined by the PCTL Bit 17 and Operating Mode Register Bit 6 settings. * For PLL enable, if PCTL Bit 17 is 0, the PLL is shutdown during Stop. Recovering from Stop requires the PLL to get locked. The PLL lock procedure duration, PLL Lock Cycles (PLC), may be in the range of 0 to 1000 cycles. This procedure occurs in parallel with the stop delay counter, and stop recovery ends when the last of these two events occurs. The stop delay counter completes count or PLL lock procedure completion. * PLC value for PLL disable is 0. * The maximum value for ETC is 4096 (maximum MF) divided by the desired internal frequency (that is, for 66 MHz it is 4096/66 MHz = 62 s). During the stabilization period, TC, TH, and TL is not constant, and their width may vary, so timing may vary as well. Periodically sampled and not 100 percent tested. Value depends on clock source: * For an external clock generator, RESET duration is measured while RESET is asserted, V CC is valid, and the EXTAL input is active and valid. * For an internal oscillator, RESET duration is measured while RESET is asserted and VCC is valid. The specified timing reflects the crystal oscillator stabilization time after power-up. This number is affected both by the specifications of the crystal and other components connected to the oscillator and reflects worst case conditions. * When the VCC is valid, but the other "required RESET duration" conditions (as specified above) have not been yet met, the device circuitry is in an uninitialized state that can result in significant power consumption and heat-up. Designs should minimize this state to the shortest possible duration. If PLL does not lose lock. V CC = 3.3 V 0.3 V; TJ = -40C to +100C, CL = 50 pF. WS = number of wait states (measured in clock cycles, number of TC). Use the expression to compute a maximum value. VIH RESET

WS is the number of wait states specified in the BCR. An expression is used to compute the number listed as the minimum or maximum value, as appropriate. Timings 100, 107 are guaranteed by design, not tested. All timings for 100 MHz are measured from 0.5 x Vcc to 0.5 x Vcc. Timing 118 is relative to the deassertion edge of RD or WR even if TA remains asserted. VCC = 3.3 V 0.3 V; TJ = -40C to +100C, CL = 50 pF

The selection guides in Figure 2-14 and Figure 2-17 are for primary selection only. Final selection should be based on the timing in the following tables. For example, the selection guide suggests that four wait states must be used for 100 MHz operation with Page Mode DRAM. However, consulting the appropriate table, a designer can evaluate whether fewer wait states might suffice by determining which timing prevents operation at 100 MHz, running the chip at a slightly lower frequency (for example, 95 MHz), using faster DRAM (if it becomes available), and manipulating control factors such as capacitive and resistive load to improve overall system performance.

The number of wait states for Page mode access is specified in the DRAM Control Register. The refresh period is specified in the DRAM Control Register. The asynchronous delays specified in the expressions are valid for the DSP56303. All the timings are calculated for the worst case. Some of the timings are better for specific cases (for example, tPC equals 4 x TC for read-after-read or write-after-write sequences). An expression is used to compute the number listed as the minimum or maximum value listed, as appropriate. BRW[1-0] (DRAM control register bits) defines the number of wait states that should be inserted in each DRAM out-of pageaccess. RD deassertion always occurs after CAS deassertion; therefore, the restricted timing is tOFF and not tGZ .

Use external bus synchronous timings only for reference to the clock and not for relative timings. Synchronous Bus Arbitration is not recommended. Use Asynchronous mode whenever possible. WS is the number of wait states specified in the BCR. If WS > 1, WR assertion refers to the next rising edge of CLKOUT. Use the expression to compute the maximum or minimum value listed, as appropriate. For timing 210, the minimum is an absolute value. T198 and T199 are valid for Address Trace mode if the ATE bit in the Operating Mode Register is set. when this mode is enabled, use the status of BR (See T212) to determine whether the access referenced by A[0-17] is internal or external.

Bit 13 in the Operating Mode Register must be set to enter Asynchronous Arbitration mode. If Asynchronous Arbitration mode is active, none of the timings in Table 2-14 is required. An expression is used to compute the maximum or minimum value listed, as appropriate. Asynchronous Arbitration mode is recommended for operation at 100 MHz. In order to guarantee timings 250, and 251, BG inputs must be asserted to different DSP56300 devices on the same bus in the non-overlap manner shown in Figure 2-26.

Figure 2-26.
Asynchronous Bus Arbitration Timing
The asynchronous bus arbitration is enabled by internal synchronization circuits on BG and BB inputs. These synchronization circuits add delay from the external signal until it is exposed to internal logic. As a result of this delay, a DSP56300 part may assume mastership and assert BB, for some time after BG is deasserted. This is the reason for timing 250. Once BB is asserted, there is a synchronization delay from BB assertion to the time this assertion is exposed to other DSP56300 components that are potential masters on the same bus. If BG input is asserted before that time, and BG is asserted and BB is deasserted, another DSP56300 component may assume mastership at the same time. Therefore, some non-overlap period between one BG input active to another BG input active is required. Timing 251 ensures that overlaps are avoided.

Unit
See the Programmer's Model section in the chapter on the HI08 in the DSP56303 User's Manual. In the timing diagrams below, the controls pins are drawn as active low. The pin polarity is programmable. This timing is applicable only if two consecutive reads from one of these registers are executed. The data strobe is Host Read (HRD) or Host Write (HWR) in the Dual Data Strobe mode and Host Data Strobe (HDS) in the Single Data Strobe mode. 5. The read data strobe is HRD in the Dual Data Strobe mode and HDS in the Single Data Strobe mode. 6. The write data strobe is HWR in the Dual Data Strobe mode and HDS in the Single Data Strobe mode. 7. The host request is HREQ in the Single Host Request mode and HRRQ and HTRQ in the Double Host Request mode. 8. The "Last Data Register" is the register at address $7, which is the last location to be read or written in data transfers. This is RXL/TXL in the Big Endian mode (HLEND = 0; HLEND is the Interface Control Register bit 7--ICR[7]), or RXH/TXH in the Little Endian mode (HLEND = 1). 9. In this calculation, the host request signal is pulled up by a 4.7 k resistor in the Open-drain mode. 10. VCC = 3.3 V 0.3 V; TJ = -40C to +100 C, CL = 50 pF 11. This timing is applicable only if a read from the "Last Data Register" is followed by a read from the RXL, RXM, or RXH registers without first polling RXDF or HREQ bits, or waiting for the assertion of the HREQ signal. 12. After the external host writes a new value to the ICR, the HI08 is ready for operation after three DSP clock cycles (3 x Tc).

For the internal clock, the external clock cycle is defined by Icyc (see Timing 7) and the ESSI Control Register. The word-length-relative frame sync signal waveform operates the same way as the bit-length frame sync signal waveform, but spreads from one serial clock before the first bit clock (same as the Bit Length Frame Sync signal) until the one before last bit clock of the first word in the frame.

If the DSP core writes to the transmit register during the last cycle before causing an underrun error, the delay is 20 ns + (0.5 x TC). An expression is used to compute the number listed as the minimum or maximum value as appropriate.

Signal names are based on configured functionality. Most pins supply a single signal. Some pins provide a signal with dual functionality, such as the MODx/IRQx pins that select an operating mode after RESET is deasserted but act as interrupt lines during operation. Some signals have configurable polarity; these names are shown with and without overbars, such as HAS/HAS. Some pins have two or more configurable functions; names assigned to these pins indicate the function for a specific configuration. For example, Pin 34 is data line H7 in non-multiplexed bus mode, data/address line HAD7 in multiplexed bus mode, or GPIO line PB7 when the GPIO function is enabled for this pin.

Signal names are based on configured functionality. Most connections supply a single signal. Some connections provide a signal with dual functionality, such as the MODx/IRQx pins that select an operating mode after RESET is deasserted but act as interrupt lines during operation. Some signals have configurable polarity; these names are shown with and without overbars, such as HAS/HAS. Some connections have two or more configurable functions; names assigned to these connections indicate the function for a specific configuration. For example, connection N2 is data line H7 in non-multiplexed bus mode, data/address line HAD7 in multiplexed bus mode, or GPIO line PB7 when the GPIO function is enabled for this pin. Unlike in the TQFP package, most of the GND pins are connected internally in the center of the connection array and act as heat sink for the chip. Therefore, except for GNDP and GND P1 that support the PLL, other GND signals do not support individual subsystems in the chip.

Design Considerations
4.1 Thermal Design Considerations
An estimate of the chip junction temperature, T J, in C can be obtained from this equation: Equation 1: T J = T A + ( P D x R JA ) Where:
TA RJA PD = = = ambient temperature C package junction-to-ambient thermal resistance C/W power dissipation in package
4
This section describes various areas to consider when incorporating the DSP56303 device into a system design.
Historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a caseto-ambient thermal resistance, as in this equation: Equation 2: R J A = R JC + R CA Where:
RJA RJC RCA = = = package junction-to-ambient thermal resistance C/W package junction-to-case thermal resistance C/W package case-to-ambient thermal resistance C/W
RJC is device-related and cannot be influenced by the user. The user controls the thermal environment to change the case-to-ambient thermal resistance, RCA. For example, the user can change the air flow around the device, add a heat sink, change the mounting arrangement on the printed circuit board (PCB) or otherwise change the thermal dissipation capability of the area surrounding the device on a PCB. This model is most useful for ceramic packages with heat sinks; some 90 percent of the heat flow is dissipated through the case to the heat sink and out to the ambient environment. For ceramic packages, in situations where the heat flow is split between a path to the case and an alternate path through the PCB, analysis of the device thermal performance may need the additional modeling capability of a system-level thermal simulation tool. The thermal performance of plastic packages is more dependent on the temperature of the PCB to which the package is mounted. Again, if the estimates obtained from RJA do not satisfactorily answer whether the thermal performance is adequate, a system-level model may be appropriate. A complicating factor is the existence of three common ways to determine the junction-to-case thermal resistance in plastic packages. * To minimize temperature variation across the surface, the thermal resistance is measured from the junction to the outside surface of the package (case) closest to the chip mounting area when that surface has a proper heat sink.

Design Considerations
* *
To define a value approximately equal to a junction-to-board thermal resistance, the thermal resistance is measured from the junction to the point at which the leads attach to the case.

If the temperature of the package case (TT) is determined by a thermocouple, thermal resistance is computed from the value obtained by the equation (TJ - TT)/PD.
As noted earlier, the junction-to-case thermal resistances quoted in this data sheet are determined using the first definition. From a practical standpoint, that value is also suitable to determine the junction temperature from a case thermocouple reading in forced convection environments. In natural convection, the use of the junction-to-case thermal resistance to estimate junction temperature from a thermocouple reading on the case of the package will yield an estimate of a junction temperature slightly higher than actual temperature. Hence, the new thermal metric, thermal characterization parameter or JT, has been defined to be (TJ - TT)/PD. This value gives a better estimate of the junction temperature in natural convection when the surface temperature of the package is used. Remember that surface temperature readings of packages are subject to significant errors caused by inadequate attachment of the sensor to the surface and to errors caused by heat loss to the sensor. The recommended technique is to attach a 40gauge thermocouple wire and bead to the top center of the package with thermally conductive epoxy.
4.2 Electrical Design Considerations
CAUTION
This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised to avoid application of any voltages higher than maximum rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for example, either GND or VCC).
Use the following list of recommendations to ensure correct DSP operation. * * * * * Provide a low-impedance path from the board power supply to each VCC pin on the DSP and from the board ground to each GND pin. Use at least six 0.01-0.1 F bypass capacitors positioned as close as possible to the four sides of the package to connect the VCC power source to GND. Ensure that capacitor leads and associated printed circuit traces that connect to the chip VCC and GND pins are less than 0.5 inch per capacitor lead. Use at least a four-layer PCB with two inner layers for VCC and GND. Because the DSP output signals have fast rise and fall times, PCB trace lengths should be minimal. This recommendation particularly applies to the address and data buses as well as the IRQA, IRQB, IRQC, IRQD, TA, and BG pins. Maximum PCB trace lengths on the order of 6 inches are recommended.
DSP56303 Technical Data, Rev. 11 4-2 Freescale Semiconductor
Power Consumption Considerations
*
Consider all device loads as well as parasitic capacitance due to PCB traces when you calculate capacitance. This is especially critical in systems with higher capacitive loads that could create higher transient currents in the VCC and GND circuits. All inputs must be terminated (that is, not allowed to float) by CMOS levels except for the three pins with internal pull-up resistors (TRST, TMS, DE). Take special care to minimize noise levels on the VCCP, GNDP, and GNDP1 pins. The following pins must be asserted after power-up: RESET and TRST. If multiple DSP devices are on the same board, check for cross-talk or excessive spikes on the supplies due to synchronous operation of the devices.
RESET
* * * * * *
must be asserted when the chip is powered up. A stable EXTAL signal should be supplied before deassertion of RESET.
At power-up, ensure that the voltage difference between the 5 V tolerant pins and the chip V CC never exceeds 3.5 V.
4.3 Power Consumption Considerations
Power dissipation is a key issue in portable DSP applications. Some of the factors affecting current consumption are described in this section. Most of the current consumed by CMOS devices is alternating current (ac), which is charging and discharging the capacitances of the pins and internal nodes. Current consumption is described by this formula: Equation 3: I = C x V x f Where:
C V f = = = node/pin capacitance voltage swing frequency of node/pin toggle Example 4-1. Current Consumption
For a Port A address pin loaded with 50 pF capacitance, operating at 3.3 V, with a 66 MHz clock, toggling at its maximum possible rate (33 MHz), the current consumption is expressed in Equation 4.
Equation 4: I = 50 x 10 - 12 x 3.3 x 33 x 10 6 = 5.48 mA The maximum internal current (ICCImax) value reflects the typical possible switching of the internal buses on bestcase operation conditions--not necessarily a real application case. The typical internal current (ICCItyp) value reflects the average switching of the internal buses on typical operating conditions. Perform the following steps for applications that require very low current consumption:
1. Set the EBD bit when you are not accessing external memory. 2. Minimize external memory accesses, and use internal memory accesses. 3. Minimize the number of pins that are switching. 4. Minimize the capacitive load on the pins. 5. Connect the unused inputs to pull-up or pull-down resistors.

One way to evaluate power consumption is to use a current-per-MIPS measurement methodology to minimize specific board effects (that is, to compensate for measured board current not caused by the DSP). A benchmark power consumption test algorithm is listed in Appendix A. Use the test algorithm, specific test current measurements, and the following equation to derive the current-per-MIPS value. Equation 5: I MIPS = I MHz = ( I typF2 - ItypF1 ) ( F2 - F1 ) Where:
ItypF2 ItypF1 F2 F1 = = = = current at F2 current at F1 high frequency (any specified operating frequency) low frequency (any specified operating frequency lower than F2)
Note: F1 should be significantly less than F2. For example, F2 could be 66 MHz and F1 could be 33 MHz. The degree of difference between F1 and F2 determines the amount of precision with which the current rating can be determined for an application.
4.4 PLL Performance Issues
The following explanations should be considered as general observations on expected PLL behavior. There is no test that replicates these exact numbers. These observations were measured on a limited number of parts and were not verified over the entire temperature and voltage ranges.
4.4.1
Phase Skew Performance
The phase skew of the PLL is defined as the time difference between the falling edges of EXTAL and CLKOUT for a given capacitive load on CLKOUT, over the entire process, temperature and voltage ranges. As defined in Figure 22, External Clock Timing, on page 2-5 for input frequencies greater than 15 MHz and the MF 4, this skew is greater than or equal to 0.0 ns and less than 1.8 ns; otherwise, this skew is not guaranteed. However, for MF < 10 and input frequencies greater than 10 MHz, this skew is between - ns and +3.2 ns. 1.4
4.4.2
Phase Jitter Performance
The phase jitter of the PLL is defined as the variations in the skew between the falling edges of EXTAL and CLKOUT for a given device in specific temperature, voltage, input frequency, MF, and capacitive load on CLKOUT. These variations are a result of the PLL locking mechanism. For input frequencies greater than 15 MHz and MF 4, this jitter is less than 0.6 ns; otherwise, this jitter is not guaranteed. However, for MF < 10 and input frequencies greater than 10 MHz, this jitter is less than 2 ns.
4.4.3
Frequency Jitter Performance
The frequency jitter of the PLL is defined as the variation of the frequency of CLKOUT. For small MF (MF < 10) this jitter is smaller than 0.5 percent. For mid-range MF (10 < MF < 500) this jitter is between 0.5 percent and approximately 2 percent. For large MF (MF > 500), the frequency jitter is 2-3 percent.

The allowed jitter on the frequency of EXTAL is 0.5 percent. If the rate of change of the frequency of EXTAL is slow (that is, it does not jump between the minimum and maximum values in one cycle) or the frequency of the jitter is fast (that is, it does not stay at an extreme value for a long time), then the allowed jitter can be 2 percent. The phase and frequency jitter performance results are valid only if the input jitter is less than the prescribed values.
