描述 Description

The CXP740056/740096/740010 is a CMOS 8-bit microcomputer integrating on a single chip an A/D converter, serial interface, timer/counter, time-base timer, capture timer/counter, remote control receive circuit, PWM output, and the like besides the basic configurations of 8-bit CPU, ROM, RAM, and I/O port.

The CXP740056/740096/740010 also provides the sleep/stop functions that enables lower power consumption.
