Preliminary
program the main Program and Data Flash memory areas. Both Program and Data Flash memories can be
independently bulk erased or erased in pages. Program Flash page erase size is 1KB. Boot and Data Flash
page erase size is 512 bytes. The Boot Flash memory can also be either bulk or page erased.
A key application-specific feature of the 56F8345 is the inclusion of two Pulse Width Modulator (PWM)
modules. These modules each incorporate three complementary, individually programmable PWM signal
output pairs (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-aligned 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 reference outputs to
synchronize the Analog-to-Digital Converters through two channels of Quad Timer C.
The 56F8345 incorporates two 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 alert 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 (SCIs); two Serial Peripheral Interfaces (SPIs); and four Quad Timers. Any of
these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function is not required. A
Flex Controller Area Network (FlexCAN) interface (CAN Version 2.0 B-compliant) and an internal
interrupt controller are also a part of the 56F8345.

56F8145 Features
The 56F8145 controller includes 128KB of Program Flash, programmable through the JTAG port, and
8KB of Data RAM. A total of 8KB of Boot Flash is incorporated for easy customer inclusion of
field-programmable software routines that can be used to program the main Program Flash memory area.
The Program Flash memory can be independently bulk erased or erased in pages; Program Flash page
erase size is 1KB. The Boot Flash page erase size is 512 bytes; Boot Flash memory can also be either bulk
or page erased.
A key application-specific feature of the 56F8145 is the inclusion of one Pulse Width Modulator (PWM)
