Item 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.
