14-bit PWM

A/D converter

Description

• Timer V: 8-bit timer

— Count-up timer with selection of six internal clock signals or event input

from external pin

— Compare-match waveform output

— Incrementing specifiable by external trigger input

• Timer X: 16-bit timer

— Count-up timer with selection of three internal clock signals or event

input from external pin

— Output compare (2 output pins)

— Input capture (4 input pins)

• Watchdog timer

— Reset signal generated by 8-bit counter overflow

Two channels on chip

• SCI1: synchronous serial interface

Choice of 8-bit or 16-bit data transfer

• SCI3: 8-bit synchronous/asynchronous serial interface

Incorporates multiprocessor communication function

Pulse-division PWM output for reduced ripple

• Can be used as a 14-bit D/A converter by connecting to an external

low-pass filter.

Successive approximations using a resistance ladder

• 8-channel analog input pins

• Conversion time: 31/ø or 62/ø per channel
