描述 Description

The CXP922P032 is a CMOS 16-bit microcomputer integrating on a single chip an A/D converter, serial interface, timer, remote control receive circuit, PWM output circuit, and as well as basic configurations like a 16-bit CPU, PROM, RAM, and I/O port.

This LSI also provides the sleep/stop functions that enable lower power consumption.
