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 56F807 is the inclusion of two Pulse Width Modulator (PWM)
modules. These modules each incorporate three complementary, individually programmable PWM signal
outputs (each module is also capable of supporting six independent PWM functions, for a total of 12 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 PWMs incorporate fault protection and cycle-by-cycle current limiting
with sufficient output drive capability to directly drive standard optoisolators. A “smoke-inhibit”,
write-once protection feature for key parameters is also included. A patented PWM waveform distortion
correction circuit is also provided. Each PWM is double-buffered and includes interrupt controls 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 56F807 incorporates two separate Quadrature Decoders 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. An 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 two Serial
Communications Interfaces (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), an internal interrupt controller, and
14 dedicated GPIO lines are also included on the 56F807.
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.
