Peripheral Circuits
Pulse Width Modulator module:
— In the 56F8335, two Pulse Width Modulator modules, each with six PWM outputs, three Current Sense
inputs, and four Fault inputs; fault-tolerant design with dead time insertion; supports both center-aligned
and edge-aligned modes
— In the 56F8135, one Pulse Width Modulator module with six PWM outputs, three Current Sense inputs
and three Fault inputs; fault-tolerant design with dead time insertion; supports both center-aligned and
edge-aligned modes
Note:
Features in italics are NOT available in the 56F8135 device.

Four 12-bit, Analog-to-Digital Converters (ADCs), which support four simultaneous conversions with
quad, 4-pin multiplexed inputs; ADC and PWM modules can be synchronized through Timer C, channels
2 and 3
Quadrature Decoder:
— In the 56F8335, two four-input Quadrature Decoders or two additional Quad Timers
— In the 56F8135, one four-input Quadrature Decoder, which works in conjunction with Quad Timer A
Temperature Sensor can be connected, on the board, to any of the ADC inputs to monitor the on-chip
temperature
Quad Timer:
— In the 56F8335, four dedicated general-purpose Quad Timers totaling six dedicated pins: Timer C with
two pins and Timer D with four pins
— In the 56F8135, two Quad Timers; Timer A and Timer C both work in conjunction with GPIO
Optional On-Chip Regulator
FlexCAN (CAN Version 2.0 B-compliant) module with 2-pin port for transmit and receive
Two Serial Communication Interfaces (SCIs), each with two pins (or four additional GPIO lines)
Up to two Serial Peripheral Interfaces (SPIs), both with configurable 4-pin port (or eight additional GPIO
lines); SPI 1 can also be used as Quadrature Decoder 1 or Quad Timer B
Computer Operating Properly (COP)/Watchdog timer
Two dedicated external interrupt pins
