CMOS 8-bit Single Chip Microcomputer
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.
