1.1.4 Peripheral Circuits

Note: Features in italics are NOT available in the 56F8123 device.

• 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

• Two 12-bit, Analog-to-Digital Converters (ADCs), which support two simultaneous conversions with dual,

4-pin multiplexed inputs; ADC and PWM modules can be synchronized through Timer C, channel 2

• Temperature Sensor can be connected, on the board, to any of the ADC inputs to monitor the on-chip

temperature

• Two 16-bit Quad Timer modules (TMR) totaling seven pins:

— In the 56F8323, Timer A works in conjunction with Quad Decoder 0 and Timer C works in conjunction

with the PWMA and ADCA

— In the 56F8123, Timer C works in conjunction with ADCA

• One Quadature Decoder which works in conjunction with Quad Timer A

• FlexCAN (CAN Version 2.0 B-compliant) module with 2-pin port for transmit and receive

• Up to two Serial Communication Interfaces (SCIs)

• Up to two Serial Peripheral Interfaces (SPIs)

• Computer Operating Properly (COP)/Watchdog timer

• One dedicated external interrupt pin

• 27 General Purpose I/O (GPIO) pins

• Integrated Power-On Reset and Low-Voltage Interrupt Module

• JTAG/Enhanced On-Chip Emulation (OnCE™) for unobtrusive, processor speed-independent, real-time

debugging

• Software-programmable, Phase Lock Loop (PLL)

• On-chip relaxation oscillator
