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 Expert
TM
(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.
