It combines, on a single chip, the processing power of a DSP and the functionality of a microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because of its low cost, configuration flexibility, and compact program code, the 56F801 is well-suited for many applications. The 56F801 includes many peripherals that are especially useful for applications such as motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and control, automotive control, engine management, noise suppression, remote utility metering, and industrial control for power, lighting, and automation. The 56800 core is based on a Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The microprocessor-style programming model and optimized instruction set allow straightforward generation of efficient, compact code for both DSP and MCU applications. The instruction set is also highly efficient for C compilers to enable rapid development of optimized control applications. The 56F801 supports program execution from either internal or external memories. Two data operands can be accessed from the on-chip Data RAM per instruction cycle. The 56F801 also provides one external dedicated interrupt lines and up to 11 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. The 56F801 controller includes 8K words (16-bit) of Program Flash and 2K words of Data Flash (each programmable through the JTAG port) with 1K words of both Program and Data RAM. A total of 2K words of Boot Flash is incorporated for easy customer-inclusion of field-programmable software routines that can be used to program the main Program and Data Flash memory areas. Both Program and Data Flash memories can be independently bulk erased or erased in page sizes of 256 words. The Boot Flash memory can also be either bulk or page erased. A key application-specific feature of the 56F801 is the inclusion of a Pulse Width Modulator (PWM) module. This modules incorporates six complementary, individually programmable PWM signal outputs to enhance motor control functionality. Complementary operation permits programmable dead-time insertion, 56F801 Technical Data For More Information On This Product, Go to: www.freescale.com 3 Freescale Semiconductor, Inc. and separate top and bottom output polarity control. The up-counter value is programmable to support a continuously variable PWM frequency. Both edge- and center-aligned synchronous pulse width control (0% to 100% modulation) are supported. The device is capable of controlling most motor types: ACIM (AC Induction Motors), both BDC and BLDC (Brush and Brushless DC motors), SRM and VRM (Switched and Variable Reluctance Motors), and stepper motors. The PWMs incorporate fault protection and cycle-bycycle current limiting with sufficient output drive capability to directly drive standard opto-isolators. A "smoke-inhibit", write-once protection feature for key parameters is also included. The PWM is doublebuffered and includes interrupt control to permit integral reload rates to be programmable from 1 to 16. The PWM modules provide a reference output to synchronize the Analog-to-Digital Converters. The 56F801 incorporates an 8 input, 12-bit Analog-to-Digital Converter (ADC). A full set of standard programmable peripherals is provided that include a Serial Communications Interface (SCI), a Serial Peripheral Interface (SPI), and two Quad Timers. Any of these interfaces can be used as General-Purpose Input/Outputs (GPIO) if that function is not required. An on-chip relaxation oscillator provides flexibility in the choice of either on-chip or externally supplied frequency reference for chip timing operations. Application code is used to select which source is to be used.

Interrupt and Program Control Signals No. of Pins 1 Signal Name IRQA Signal Type Input (Schmitt) State During Reset Input Signal Description External Interrupt Request A--The IRQA input is a synchronized external interrupt request that indicates that an external device is requesting service. It can be programmed to be level-sensitive or negative-edge- triggered. Reset--This input is a direct hardware reset on the processor. When RESET is asserted low, the hybrid controller is initialized and placed in the Reset state. A Schmitt trigger input is used for noise immunity. When the RESET pin is deasserted, the initial chip operating mode is latched from the EXTBOOT pin. The internal reset signal will be deasserted synchronous with the internal clocks, after a fixed number of internal clocks. To ensure complete hardware reset, RESET and TRST should be asserted together. The only exception occurs in a debugging environment when a hardware device reset is required and it is necessary not to reset the OnCE/JTAG module. In this case, assert RESET, but do not assert TRST. 1 RESET Input (Schmitt) Input 2.5 Pulse Width Modulator (PWM) Signals Table 8.

The term "5-volt tolerant" refers to the capability of an I/O pin, built on a 3.3V compatible process technology, to withstand a voltage up to 5.5V without damaging the device. Many systems have a mixture of devices designed for 3.3V and 5V power supplies. In such systems, a bus may carry both 3.3V and 5V- compatible I/O voltage levels (a standard 3.3V I/O is designed to receive a maximum voltage of 3.3V 10% during normal operation without causing damage). This 5V-tolerant capability therefore offers the power savings of 3.3V I/O levels while being able to receive 5V levels without being damaged. Absolute maximum ratings given in Table 14 are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent damage to the device. The 56F801 DC and AC electrical specifications are preliminary and are from design simulations. These specifications may not be fully tested or guaranteed at this early stage of the product life cycle. Finalized specifications will be published after complete characterization and device qualifications have been completed. 56F801 Technical Data For More Information On This Product, Go to: www.freescale.com 11 Freescale Semiconductor, Inc. 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 voltage level. Freescale Semiconductor, Inc... Table 14.

Junction to case Junction to center of case I/O pin power dissipation Power dissipation Junction to center of case Notes: 1. 2. Theta-JA determined on 2s2p test boards is frequently lower than would be observed in an application. Determined on 2s2p thermal test board. Junction to ambient thermal resistance, Theta-JA (RJA) was simulated to be equivalent to the JEDEC specification JESD51-2 in a horizontal configuration in natural convection. Theta-JA was also simulated on a thermal test board with two internal planes (2s2p where s is the number of signal layers and p is the number of planes) per JESD51-6 and JESD51-7. The correct name for Theta-JA for forced convection or with the non-single layer boards is Theta-JMA. Junction to case thermal resistance, Theta-JC (RJC ), was simulated to be equivalent to the measured values using the cold plate technique with the cold plate temperature used as the "case" temperature. The basic cold plate measurement technique is described by MIL-STD 883D, Method 1012.1. This is the correct thermal metric to use to calculate thermal performance when the package is being used with a heat sink. Thermal Characterization Parameter, Psi-JT (JT ), is the "resistance" from junction to reference point thermocouple on top center of case as defined in JESD51-2. JT is a useful value to use to estimate junction temperature in steady state customer environments. Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site (board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and board thermal resistance. See Section 5.1 from more details on thermal design considerations. 3. 4. 5. 6. 56F801 Technical Data For More Information On This Product, Go to: www.freescale.com 13 Freescale Semiconductor, Inc. 3.2 DC Electrical Characteristics Table 17.

All inputs 0.2V from rail; outputs unloaded. All ports configured as inputs; measured with all modules enabled. 8. Wait IDD measured using external square wave clock source (fosc = 8MHz) into XTAL; all inputs 0.2V from rail; no DC loads; less than 50pF on all outputs. CL = 20pF on EXTAL; all ports configured as inputs; EXTAL capacitance linearly affects wait IDD; measured with PLL enabled. 9. This low voltage interrupt monitors the VDDA external power supply. VDDA is generally connected to the same potential as VDD via separate traces. If VDDA drops below VEIO, an interrupt is generated. Functionality of the device is guaranteed under transient conditions when VDDA>VEIO (between the minimum specified VDD and the point when the VEIO interrupt is generated). 10. This low voltage interrupt monitors the internally regulated core power supply. If the output from the internal voltage is regulator drops below VEIC, an interrupt is generated. Since the core logic supply is internally regulated, this interrupt will not be generated unless the external power supply drops below the minimum specified value (3.0V). 11. Power-on reset occurs whenever the internally regulated 2.5V digital supply drops below 1.5V typical. While power is ramping up, this signal remains active for as long as the internal 2.5V is below 1.5V typical no matter how long the ramp up rate is. The internally regulated voltage is typically 100 mV less than VDD during ramp up until 2.5V is reached, at which time it self regulates. 56F801 Technical Data For More Information On This Product, Go to: www.freescale.com 15 Freescale Semiconductor, Inc. 160 IDD Digital IDD Analog IDD Total 120 IDD (mA) 80 Freescale Semiconductor, Inc... 40 0 10 20 30 40 Freq.

Flash Mass Erase Cycle 3.5 External Clock Operation The 56F801 device clock is derived from either 1) an internal crystal oscillator circuit working in conjunction with an external crystal, 2) an external frequency source, or 3) an on-chip relaxation oscillator. To generate a reference frequency using the internal crystal oscillator circuit, a reference crystal external to the chip must be connected between the EXTAL and XTAL pins. Paragrahs 3.5.1 and 3.5.4 describe these methods of clocking. Whichever type of clock derivation is used provides a reference signal to a phaselocked loop (PLL) within the 56F801. In turn, the PLL generates a master reference frequency that determines the speed at which chip operations occur. Application code can be set to change the frequency source between the relaxation oscillator and crystal oscillator or external source, and power down the relaxation oscillator if desired. Selection of which clock is used is determined by setting the PRECS bit in the PLLCR (phase-locked loop control register) word (bit 2). If the bit is set to 1, the external crystal oscillator circuit is selected. If the bit is set to 0, the internal relaxation oscillator is selected, and this is the default value of the bit when power is first applied. 3.5.1 Crystal Oscillator The internal oscillator is also designed to interface with a parallel-resonant crystal resonator in the frequency range specified for the external crystal in Table 23. Figure 9 shows a recommended crystal oscillator circuit. Follow the crystal supplier's recommendations when selecting a crystal, since crystal parameters determine the component values required to provide maximum stability and reliable start-up. The crystal and associated components should be mounted as close as possible to the EXTAL and XTAL pins to minimize output distortion and start-up stabilization time. The internal 56F80x oscillator circuitry is designed to have no external load capacitors present. As shown in Figure 10 no external load capacitors should be used. 20 56F801 Technical Data For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. External Clock Operation The 56F80x components internally are modeled as a parallel resonant oscillator circuit to provide a capacitive load on each of the oscillator pins (XTAL and EXTAL) of 10pF to 13pF over temperature and process variations. Using a typical value of internal capacitance on these pins of 12pF and a value of 3pF as a typical circuit board trace capacitance the parallel load capacitance presented to the crystal is 9pF as determined by the following equation: CL1 * CL2 CL = CL1 + CL2 + Cs = 12 + 12 12 * 12 + 3 = 6 + 3 = 9pF Freescale Semiconductor, Inc... This is the value load capacitance that should be used when selecting a crystal and determining the actual frequency of operation of the crystal oscillator circuit. EXTAL XTAL Rz fc Recommended External Crystal Parameters: Rz = 1 to 3 M fc = 8MHz (optimized for 8MHz) Figure 9. External Crystal Oscillator Circuit 3.5.2 Ceramic Resonator It is also possible to drive the internal oscillator with a ceramic resonator, assuming the overall system design can tolerate the reduced signal integrity. In Figure 10, a typical ceramic resonator circuit is shown. Refer to supplier's recommendations when selecting a ceramic resonator and associated components. The resonator and components should be mounted as close as possible to the EXTAL and XTAL pins. The internal 56F80x oscillator circuitry is designed to have no external load capacitors present. As shown in Figure 9 no external load capacitors should be used. EXTAL XTAL Rz fc Recommended Ceramic Resonator Parameters: Rz = 1 to 3 M fc = 8MHz (optimized for 8MHz) Figure 10. Connecting a Ceramic Resonator Note: Motorola recommends only two terminal ceramic resonators vs. three terminal resonators (which contain an internal bypass capacitor to ground). 3.5.3 External Clock Source The recommended method of connecting an external clock is given in Figure 11. The external clock source is connected to XTAL and the EXTAL pin is grounded. 56F801 Technical Data For More Information On This Product, Go to: www.freescale.com 21 Freescale Semiconductor, Inc. 56F801 XTAL EXTAL External Clock VSS Figure 11.

External Clock Timing 3.5.4 Use of On-Chip Relaxation Oscillator An internal relaxation oscillator can supply the reference frequency when an external frequency source or crystal are not used. During a 56F801 boot or reset sequence, the relaxation oscillator is enabled by default, and the PRECS bit in the PLLCR word is set to 0 (Section 3.5). If an external oscillator is connected, the relaxation oscillator can be deselected instead by setting the PRECS bit in the PLLCR to 1. When this occurs, the PRECSS bit in the PLLSR (prescaler clock select status register) data word also sets to 1. If a changeover between internal and external oscillators is required at startup, internal device circuits compensate for any asynchronous transitions between the two clock signals so that no glitches occur in the resulting master clock to the chip. When changing clocks, the user must ensure that the clock source is not switched until the desired clock is enabled and stable. To compensate for variances in the device manufacturing process, the accuracy of the relaxation oscillator can be incrementally adjusted to within 0.25% of 8MHz by trimming an internal capacitor. Bits 0-7 of the IOSCTL (internal oscillator control) word allow the user to set in an additional offset (trim) to this preset value to increase or decrease capacitance. The default value of this trim is 128 units, making the power-up default capacitor size 432 units. Each unit added or deleted changes the output frequency by about 0.2%, allowing incremental adjustment until the desired frequency accuracy is achieved. 22 For More Information On This Product, Go to: www.freescale.com 56F801 Technical Data Freescale Semiconductor, Inc.

Thermal Design Considerations Part 5 Design Considerations 5.1 Thermal Design Considerations An estimation of the chip junction temperature, TJ, in C can be obtained from the equation: Equation 1: Where: TJ = T A + ( P D x R JA ) Freescale Semiconductor, Inc... TA = ambient temperature C RJA = package junction-to-ambient thermal resistance C/W PD = 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: Equation 2: Where: RJA = RJC + R CA RJA = package junction-to-ambient thermal resistance C/W RJC = package junction-to-case thermal resistance C/W RCA = 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 the 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 estimations obtained from RJA do not satisfactorily answer whether the thermal performance is adequate, a system level model may be appropriate. Definitions: A complicating factor is the existence of three common definitions for determining the junction-to-case thermal resistance in plastic packages: * Measure the thermal resistance 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. This is done to minimize temperature variation across the surface. Measure the thermal resistance from the junction to where the leads are attached to the case. This definition is approximately equal to a junction to board thermal resistance. Use the value obtained by the equation (TJ - TT)/PD where TT is the temperature of the package case determined by a thermocouple.

The thermal characterization parameter is measured per JESD51-2 specification using a 40-gauge type T thermocouple epoxied to the top center of the package case. The thermocouple should be positioned so that the thermocouple junction rests on the package. A small amount of epoxy is placed over the thermocouple junction and over about 1mm of wire extending from the junction. The thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects of the thermocouple wire. When heat sink is used, the junction temperature is determined from a thermocouple inserted at the interface between the case of the package and the interface material. A clearance slot or hole is normally required in the heat sink. Minimizing the size of the clearance is important to minimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. Because of the experimental difficulties with this technique, many engineers measure the heat sink temperature and then back-calculate the case temperature using a separate measurement of the thermal resistance of the interface. From this case temperature, the junction temperature is determined from the junction-to-case thermal resistance. Freescale Semiconductor, Inc... 5.2 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 voltage level. Use the following list of considerations to assure correct operation: * * Provide a low-impedance path from the board power supply to each VDD pin on the hybrid controller, and from the board ground to each VSS (GND) pin. The minimum bypass requirement is to place 0.1 F capacitors positioned as close as possible to the package supply pins. The recommended bypass configuration is to place one bypass capacitor on each of the ten VDD/VSS pairs, including VDDA/VSSA. Ceramic and tantalum capacitors tend to provide better performance tolerances. Ensure that capacitor leads and associated printed circuit traces that connect to the chip VDD and VSS (GND) pins are less than 0.5 inch per capacitor lead. Bypass the VDD and VSS layers of the PCB with approximately 100 F, preferably with a highgrade capacitor such as a tantalum capacitor. Because the controller's output signals have fast rise and fall times, PCB trace lengths should be minimal. Consider all device loads as well as parasitic capacitance due to PCB traces when calculating capacitance. This is especially critical in systems with higher capacitive loads that could create higher transient currents in the VDD and GND circuits. Take special care to minimize noise levels on the VREF, VDDA and VSSA pins. * * * * * 40 For More Information On This Product, Go to: www.freescale.com 56F801 Technical Data Freescale Semiconductor, Inc. Electrical Design Considerations * Designs that utilize the TRST pin for JTAG port or OnCE module functionality (such as development or debugging systems) should allow a means to assert TRST whenever RESET is asserted, as well as a means to assert TRST independently of RESET. TRST must be asserted at power up for proper operation. Designs that do not require debugging functionality, such as consumer products, TRST should be tied low. Because the Flash memory is programmed through the JTAG/OnCE port, designers should provide an interface to this port to allow in-circuit Flash programming. * Freescale Semiconductor, Inc... 56F801 Technical Data For More Information On This Product, Go to: www.freescale.com 41 Freescale Semiconductor, Inc.
