56F8037/56F8027 Features

1.1.4 Peripheral Circuits for 56F8037/56F8027

• One multi-function six-output Pulse Width Modulator (PWM) module

— Up to 96MHz PWM operating clock

— 15 bits of resolution

— Center-aligned and Edge-aligned PWM signal mode

— Four programmable fault inputs with programmable digital filter

— Double-buffered PWM registers

— Each complementary PWM signal pair allows selection of a PWM supply source from:

– PWM generator

– External GPIO

– Internal timers

– Analog comparator outputs

– ADC conversion result which compares with values of ADC high- and low-limit registers to set

PWM output

• Two independent 12-bit Analog-to-Digital Converters (ADCs)

— 2 x 8 channel inputs

— Supports both simultaneous and sequential conversions

— ADC conversions can be synchronized by both PWM and timer modules

— Sampling rate up to 2.67MSPS

— 16-word result buffer registers

• Two 12-bit Digital-to-Analog Converters (DACs)

— 2 microsecond settling time when output swing from rail to rail

— Automatic waveform generation generates square, triangle and sawtooth waveforms with

programmable period, update rate, and range

• Two 16-bit multi-purpose Quad Timer modules (TMRs)

— Up to 96MHz operating clock

— Eight independent 16-bit counter/timers with cascading capability

— Each timer has capture and compare capability

— Up to 12 operating modes

• Two Queued Serial Communication Interfaces (QSCIs) with LIN Slave functionality

— Full-duplex or single-wire operation

— Two receiver wake-up methods:

– Idle line

– Address mark

— Four-bytes-deep FIFOs are available on both transmitter and receiver

• Two Queued Serial Peripheral Interfaces (QSPIs)
