1.2 56F803 Description
The 56F803 is a member of the 56800 core-based family of processors. 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 56F803 is well-suited for many applications. The 56F803 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 MCU-style programming model and
optimized instruction set allow straightforward generation of efficient, compact device and control code.
The instruction set is also highly efficient for C compilers to enable rapid development of optimized
control applications.
The 56F803 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 56F803 also provides two external
dedicated interrupt lines, and up to 16 General Purpose Input/Output (GPIO) lines, depending on
peripheral configuration.
The 56F803 controller includes 31.5K words (16-bit) of Program Flash and 4K words of Data Flash (each
programmable through the JTAG port) with 512 words of Program RAM and 2K words of Data RAM. It
also supports program execution from external memory.
A total of 2K words of Boot Flash is incorporated for easy customer-inclusion of field-programmable
56F803 Technical Data, Rev. 16

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 56F803 is the inclusion of a Pulse Width Modulator (PWM)
module. This module incorporates three complementary, individually programmable PWM signal outputs
(the module is also capable of supporting three independent PWM functions, for a total of six PWM
outputs) to enhance motor control functionality. Complementary operation permits programmable dead
time insertion, distortion correction via current sensing by software, and separate top and bottom output
polarity control. The up-counter value is programmable to support a continuously variable PWM
frequency. Edge- and center-aligned synchronous pulse width control (0% to 100% modulation) is
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 PWM incorporates fault protection and cycle-by-cycle current limiting
with sufficient output drive capability to directly drive standard opto-isolators. A “smoke-inhibit”,
write-once protection feature for key parameters and patented PWM waveform distortion correction
circuit are also provided. The PWM is double-buffered and includes interrupt controls to permit integral
reload rates to be programmable from 1 to 16. The PWM module provides a reference output to
synchronize the ADC.
The 56F803 incorporates a separate Quadrature Decoder capable of capturing all four transitions on the
two-phase inputs, permitting generation of a number proportional to actual position. Speed computation
capabilities accommodate both fast and slow moving shafts. The integrated watchdog timer in the
Quadrature Decoder can be programmed with a time-out value to alarm when no shaft motion is detected.
Each input is filtered to ensure only true transitions are recorded.
This controller also provides a full set of standard programmable peripherals that include a Serial
Communications Interface (SCI), one Serial Peripheral Interface (SPI), and four Quad Timers. Any of
these interfaces can be used as General Purpose Input/Outputs (GPIO) if that function is not required. A
Controller Area Network interface (CAN Version 2.0 A/B-compliant) and an internal interrupt controller
are also included on the 56F803.
1.3 State of the Art Development Environment
•
•
Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use
component-based software application creation with an expert knowledge system.
The Code Warrior Integrated Development Environment is a sophisticated tool for code navigation,
compiling, and debugging. A complete set of evaluation modules (EVMs) and development system cards
will support concurrent engineering. Together, PE, Code Warrior and EVMs create a complete, scalable
tools solution for easy, fast, and efficient development.

Signal Description
Reset—This input is a direct hardware reset on the processor.
When RESET is asserted low, the 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 a 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.

Part 3 Specifications
3.1 General Characteristics
The 56F803 is fabricated in high-density CMOS with 5-V tolerant TTL-compatible digital inputs. The
term “5-V 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 3-1 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 56F803 DC/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.
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.

Notes:
1.
Theta-JA determined on 2s2p test boards is frequently lower than would be observed in an application.
Determined on 2s2p thermal test board.
2.
Junction to ambient thermal resistance, Theta-JA (RθJA) 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.
3.
Junction to case thermal resistance, Theta-JC (RθJC ), 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.
56F803 Technical Data, Rev. 16

4.
Thermal Characterization Parameter, Psi-JT (ΨJT ), is the “resistance” from junction to reference point
thermocouple on top center of case as defined in JESD51-2. ΨJT is a useful value to use to estimate junction
temperature in steady state customer environments.
5.
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.

8. 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).
9. 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).
10. 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 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 100mV less than VDD during ramp-up, until 2.5V is reached, at which time it
self-regulates.

External Clock Operation
3.5 External Clock Operation
The 56F803 system clock can be derived from an external crystal or an external system clock signal. To
generate a reference frequency using the internal oscillator, a reference crystal must be connected between
the EXTAL and XTAL pins.
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 3-9. In Figure 3-7 a recommended crystal
oscillator circuit is shown. Follow the crystal supplier’s recommendations when selecting a crystal,
because 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 3-8 no external load capacitors should be used.
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
12 * 12
+ Cs =
+ 3 = 6 + 3 = 9pF
12 + 12
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.

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 3-8, 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 3-7 no external load capacitors should be used.

(which contain an internal bypass capacitor to ground).

The recommended method of connecting an external clock is given in Figure 3-9. The external clock
source is connected to XTAL and the EXTAL pin is grounded.

1. Timing is both wait state and frequency dependent. In the formulas listed, WS = the number of wait states and
T = Clock Period. For 80MHz operation, T = 12.5ns.
2. Parameters listed are guaranteed by design.
To calculate the required access time for an external memory for any frequency < 80Mhz, use this formula:
Top = Clock period @ desired operating frequency
WS = Number of wait states
Memory Access Time = (Top*WS) + (Top- 11.5)

1. In the formulas, T = clock cycle. For an operating frequency of 80MHz, T = 12.5ns.
2. Circuit stabilization delay is required during reset when using an external clock or crystal oscillator in two cases:
• After power-on reset
• When recovering from Stop state
3. The minimum is specified for the duration of an edge-sensitive IRQA interrupt required to recover from the Stop state. This is
not the minimum required so that the IRQA interrupt is accepted.
4. The interrupt instruction fetch is visible on the pins only in Mode 3.
5. Parameters listed are guaranteed by design.

1. If Wakeup glitch filter is enabled during the design initialization and also CAN is put into SLEEP mode then, any bus event
(on MSCAN_RX pin) whose duration is less than 5 micro seconds is filtered away. However, a valid CAN bus wakeup detection takes place for a wakeup pulse equal to or greater than 5 microseconds. The value of 5 microseconds originates from the
fact that the CAN wakeup message consists of 5 dominant bits at the highest possible baud rate of 1Mbps.

Thermal Design Considerations
Please see www.freescale.com for the most current case outline.
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: TJ = T A + ( P D × RθJA )
Where:
TA = ambient temperature °C
RθJA = 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: RθJA = R θJC + R θCA
Where:
RθJA = package junction-to-ambient thermal resistance °C/W
RθJC = package junction-to-case thermal resistance °C/W
RθCA = package case-to-ambient thermal resistance °C/W
RθJC is device-related and cannot be influenced by the user. The user controls the thermal environment to
change the case-to-ambient thermal resistance, RθCA. 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 RθJA 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
