1.1.4 Peripheral Circuits
Note: Features in italics are NOT available in the 56F8156 device.
• Pulse Width Modulator:
— In the 56F8356, two Pulse Width Modulator modules, each 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
— In the 56F8156, 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
• 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 56F8356, two four-input Quadrature Decoders or two additional Quad Timers
— In the 56F8156, 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 56F8356, four dedicated general-purpose Quad Timers totaling three dedicated pins: Timer C
with one pin and Timer D with two pins
— In the 56F8156, 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
