Peripheral Circuits

Note: Features in italics are NOT available in the 56F8167 device.

•

Pulse Width Modulator:

— In the 56F8367, 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 56F8167, 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 56F8367, two four-input Quadrature Decoders or two additional Quad Timers

— In the 56F8167, 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 56F8367, four dedicated general-purpose Quad Timers totaling six dedicated pins: Timer C with

two pins and Timer D with four pins

— In the 56F8167, two general-purpose Quad Timers; Timer A works in conjunction with Quadrature

Decoder 0 or GPIO and Timer C works in conjunction with GPIO

•

Up to two FlexCAN (CAN Version 2.0 B-compliant) modules with 2-pin port for transmit and receive
