Specification

Serial

communication

interface

• SCI3: 8-bit synchronous/asynchronous serial interface

Incorporates multiprocessor communication function

10-bit PWM

Pulse-division PWM output for reduced ripple

• Can be used as a 10-bit D/A converter by connecting to an external low-

pass filter.

A/D converter

Successive approximations using a resistance ladder

• 8-channel analog input pins

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

LCD controller/

driver

LCD controller/driver equipped with a maximum of 32 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 4-bit units

Power-on reset

and low-voltage

detect circuits

(H8/38124 Group

only)

Power-on reset circuit

• An internal reset signal can be issued at power-on by connecting an

external capacitor.

Low-voltage detect circuit

• Monitors the power supply voltage and issues an internal reset signal or

interrupt if the voltage goes below or above a specified range.
