1-6 dsp56307 technical data motorola signals/connections external memory expansion port (port a) external memory expansion port (port a) note: when the dsp56307 enters a low-power standby mode (stop or wait), it releases bus mastership and tri-states the relevant port a signals: a0ea17, d0ed23, aa0/ras0 eaa3/ras3 , rd , wr , bb , cas , bclk, bclk . external address bus pinit nmi input input input pll initial ?during assertion of reset , the value of pinit is written into the pll enable (pen) bit of the pll control (pctl) register, determining whether the pll is enabled or disabled. nonmaskable interrupt ?after reset deassertion and during normal instruction processing, this schmitt-trigger input is the negative-edge-triggered nmi request internally synchronized to clkout. table 1-6 external address bus signals signal name type state during reset signal description a0ea17 output tri-stated address bus ?when the dsp is the bus master, a0ea17 are active-high outputs that specify the address for external program and data memory accesses. otherwise, the signals are tri-stated. to minimize power dissipation, a0ea17 do not change state when external memory spaces are not being accessed. table 1-5 phase-locked loop signals (continued) signal name type state during reset signal description

1-8 dsp56307 technical data motorola signals/connections external memory expansion port (port a) ta input ignored input transfer acknowledge ?if the dsp56307 is the bus master and there is no external bus activity, or the dsp56307 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) may 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. in order 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 omr. ta functionality may not be used while performing dram type accesses; otherwise, improper operation may result. table 1-8 external bus control signals (continued) signal name type state during reset signal description
signals/connections external memory expansion port (port a) motorola dsp56307 technical data 1-9 br output output (deasserted) bus request ?br is an active-low output, never tri-stated. br is 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 dsp56307 is a bus master or a bus slave. bus parking allows br to be deasserted even though the dsp56307 is the bus master. (see the description of bus parking in the bb signal description.) the bus request hole (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 only affected 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 input ignored input bus grant ?bg is an active-low input. bg must be asserted/deasserted synchronous to clkout for proper operation. bg is asserted by an external bus arbitration circuit when the dsp56307 becomes the next bus master. when bg is asserted, the dsp56307 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 dsp56307 technical data (the data sheet). an alternate mode can be invoked: set the asynchronous bus arbitration enable (abe) bit (bit 13) in the omr. 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. table 1-8 external bus control signals (continued) signal name type state during reset signal description
1-10 dsp56307 technical data motorola signals/connections external memory expansion port (port a) bb input/ output input bus busy ?bb is a bidirectional active-low input/output and must be asserted and deasserted synchronous to clkout. bb 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. the deassertion of bb is done by an active pull-up method (i.e., bb is driven high and then released and held high by an external pull-up resistor). the default operation of this bit requires a setup and hold time as specified in the dsp56307 technical data sheet . an alternate mode can be invoked: set the abe bit (bit 13) in the omr. when this bit is set, bg and bb are synchronized internally. see bg for additional information. bb requires an external pull-up resistor. cas output 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. bclk output tri-stated bus clock ?when the dsp is the bus master, bclk is an active-high output. bclk is active as a sampling signal when the program address tracing mode is enabled (i.e., the ate bit in the omr is set). when bclk is active and synchronized to clkout by the internal pll, bclk precedes clkout by one-fourth of a clock cycle. the bclk rising edge may be used to sample the internal program memory access on the a0ea23 address lines. bclk output tri-stated bus clock not ?when the dsp is the bus master, bclk is an active-low output and is the inverse of the bclk signal. otherwise, the signal is tri-stated. table 1-8 external bus control signals (continued) signal name type state during reset signal description
signals/connections interrupt and mode control motorola dsp56307 technical data 1-11 interrupt and mode control the interrupt and mode control signals select the chip?s operating mode as it comes out of hardware reset. after reset is deasserted, these inputs are hardware interrupt request lines. table 1-9 interrupt and mode control signal name type state during reset signal description reset input input reset ?reset is an active-low, schmitt-trigger input. deassertion of reset is internally synchronized to clkout. when asserted, the chip is placed in the reset state and the internal phase generator is reset. the schmitt-trigger input allows a slowly rising input (such as a capacitor charging) to reset the chip reliably. if reset is deasserted synchronous to clkout, exact start-up timing is guaranteed, allowing multiple processors to start synchronously and operate together in lock-step. 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 power up. moda irqa input input input mode select a ?moda is an active-low schmitt-trigger input, internally synchronized to clkout. moda, modb, modc, and modd select one of 16 initial chip operating modes, latched into the omr when the reset signal is deasserted. external interrupt request a ?after reset, this input becomes a level-sensitive or negative-edge-triggered, maskable interrupt request input during normal instruction processing. if irqa is asserted synchronous to clkout, multiple processors can be resynchronized using the wait instruction and asserting irqa to exit the wait state. if the processor is in the stop standby state and irqa is asserted, the processor will exit the stop state.

motorola dsp56307 technical data 2-1 section 2 specifications introduction the dsp56307 is fabricated in high-density cmos with transistor-transistor logic (ttl) compatible inputs and outputs. the dsp56307 specifications are preliminary from design simulations and may not be fully tested or guaranteed at this early stage of the product life cycle. finalized specifications will be published after full characterization and device qualifications are complete. maximum ratings note: 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 will never occur 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. 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 (e.g., either gnd or v cc ).

motorola dsp56307 technical data 4-1 section 4 design considerations thermal design considerations an estimate of the chip junction temperature, t j , in c can be obtained from this equation: equation 1: where: t a = ambient temperature ?c r q ja = package junction-to-ambient thermal resistance ?c/w p d = power dissipation in package historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance, as in this equation: equation 2: where: r q ja = package junction-to-ambient thermal resistance ?c/w r q jc = package junction-to-case thermal resistance ?c/w r q ca = package case-to-ambient thermal resistance ?c/w r q jc is device-related and cannot be influenced by the user. the user controls the thermal environment to change the case-to-ambient thermal resistance, r q ca . 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% 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 r q ja do not satisfactorily answer whether the thermal performance is adequate, a system-level model may be appropriate. t j t a p d r q ja () + = r q ja r q jc r q ca + =
section 4-2 dsp56307 technical data motorola design considerations thermal design considerations 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. to define a value approximately equal to a junction-to-board thermal resistance, the thermal resistance is measured from the junction to where the leads are attached to the case. if the temperature of the package case (t t ) is determined by a thermocouple, the thermal resistance is computed from the value obtained by the equation (t j - t t )/p d . 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 hotter than actual temperature. hence, the new thermal metric, thermal characterization parameter or y jt , has been defined to be (t j - t t )/p d . 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 40-gauge thermocouple wire and bead to the top center of the package with thermally conductive epoxy.
design considerations electrical design considerations motorola dsp56307 technical data section 4-3 electrical design considerations use the following list of recommendations to insure correct dsp operation. provide a low-impedance path from the board power supply to each v cc pin on the dsp and from the board ground to each gnd pin. use at least six 0.01e0.1 m f bypass capacitors positioned as close as possible to the four sides of the package to connect the v cc power source to gnd. insure that capacitor leads and associated printed circuit traces that connect to the chip v cc and gnd pins are less than 0.5 inch per capacitor lead. use at least a four-layer pcb with two inner layers for v cc 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. 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 v cc and gnd circuits. all inputs must be terminated (i.e., 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 v ccp , gnd p , and gnd p1 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. 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 (e.g., either gnd or v cc ).
section 4-4 dsp56307 technical data motorola design considerations power consumption considerations reset must be asserted when the chip is powered up. a stable extal signal should be supplied before deassertion of reset. power consumption considerations power dissipation is a key issue in portable dsp applications. some of the factors which affect 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: where: c = node/pin capacitance v = voltage swing f = frequency of node/pin toggle the maximum internal current (i cci max) value reflects the typical possible switching of the internal buses on best-case operation conditions?not necessarily a real application case. the typical internal current (i ccityp ) 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: set the ebd bit when you are not accessing external memory. minimize external memory accesses, and use internal memory accesses. minimize the number of pins that are switching. minimize the capacitive load on the pins. connect the unused inputs to pull-up or pull-down resistors. disable unused peripherals. disable unused pin activity (e.g., clkout, xtal). example 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 this equation: equation 4: i cvf = i5010 12 e 3.3 33 10 6 5.48 ma ==
design considerations pll performance issues motorola dsp56307 technical data section 4-5 one way to evaluate power consumption is to use a current per mips measurement methodology to minimize specific board effects (i.e., to compensate for measured board current not caused by the dsp). a benchmark power consumption test algorithm is listed in appendix appendix a power consumption benchmark . use the test algorithm, specific test current measurements, and the following equation to derive the current per mips value. equation 5: where : i typf2 = current at f2 i typf1 = current at f1 f2 = high frequency (any specified operating frequency) f1 = 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. 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. 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 2-2 on page section 2-7 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 - 1.4 ns and +3.2 ns. i mips i mhz i typf2 i typf1 e () f2 f1 e () ==
section 4-6 dsp56307 technical data motorola design considerations pll performance issues 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. 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%. for mid-range mf (10 < mf < 500) this jitter is between 0.5% and approximately 2%. for large mf (mf > 500), the frequency jitter is 2e3%. input (extal) jitter requirements the allowed jitter on the frequency of extal is 0.5%. if the rate of change of the frequency of extal is slow (i.e., it does not jump between the minimum and maximum values in one cycle) or the frequency of the jitter is fast (i.e., it does not stay at an extreme value for a long time), then the allowed jitter can be 2%. the phase and frequency jitter performance results are valid only if the input jitter is less than the prescribed values.
