Peripheral Circuits
Pulse Width Modulator module:
— In the 56F8355, 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 56F8155, 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 56F8155 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 56F8355, two four-input Quadrature Decoders or two additional Quad Timers
— In the 56F8155, 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:
