1.2 56F803 Description
The 56F803 is a member of the 56800 core-b ased family of hybrid contr ollers. It combines, on a singl e 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-su ited for many ap plicati ons. The 56F803 inc ludes many periph erals tha t
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 opera tions per inst ructi on cycle . The MCU-style programmi ng model and
optimized instruc tion se t allo w straight forw ard gene rati on of ef f icien t, compact DSP and co ntrol code. The
instruction set is also highly efficient for C compilers to enable rapid development of optimized control
applications.
The 56F803 supports pro gra m e xec uti on 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 interrup t lines, a nd up to 16 Gen eral Pu rpose Inpu t/Output ( GPIO) line s, depending on periphe ral
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
software routines that can be used to program the main Program and Data Flash memory areas. Both

Program and Data Flash memories can be inde pendently bulk–erased or eras ed i n page siz es of 256 word s.
The Boot Flash memory can also be either bulk- or page
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 suppor ting three i ndependent PWM functi ons, for a to tal of six PWM outpu ts)
to enhance motor control functionality. Complementary operation permits programmable dead time
insertion, distor tion co rrect ion via current sensin g by sof tware, an d separa te top and bottom outp ut pol arit y
control. The up-counter value is programmable to support a continuously variable PWM frequency. Edgeand 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 VR M (Switch ed and Variable Reluctance Mot ors), and s tepper mo tors.
The PWM incorporates fault protection and cycle-by-cycle current limiting with sufficient output drive
capability to direc tly drive st andard opto-i solators. A “smoke-inhibit”, write-o nce protecti on feature f or 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 incorpor ates a separa te Quadrature Decode r capable o f capturing all four transit ions 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

This controller also provides a full set of standard programmable peripherals that include a Serial
Communications Inte rface (S CI), one Serial Peripher al Inte rface (S PI), an d four Qua d T imer s. Any of t hese
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-touse component-based software application creation with an expert knowledge system.
• The Code Warrior Integrated Deve lopment Enviro nment is a sophi sticated to ol for code na vigation,

General Characteristics
Part 3 Specifications
3.1 General Characteristics
The 56F803 is fabrica ted in high-de nsity CMOS with 5- V tolerant TTL-c ompatible d igital i nputs. The te rm
“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
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 19 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.
