Description

Serial

communication

interface

Three serial communication interface channels on chip

• SCI1: Synchronous serial interface

Choice of 8-bit or 16-bit transfer data

• SCI3-1: 8-bit synchronous/asynchronous serial interface

Incorporates multiprocessor communication function

• SCI3-2: 8-bit synchronous/asynchronous serial interface

Incorporates multiprocessor communication function

14-bit PWM

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.

A/D converter

Successive approximations using a resistance ladder

• 12-channel analog input pins

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

LCD

controller/driver

LCD controller/driver equipped with a maximum of 40 segment pins and four

common pins

• Choice of four duty cycles (static, 1/2, 1/3, or 1/4)

• Segment pins can be switched to general-purpose port function in 8-bit units

LCD drive power

supply

Step-up constant-voltage power supply allows LCD display.(H8/3887 Series only)
