CMOS 8-bit Single Chip Microcomputer
Description
The CXP84120/84124 is a CMOS 8-bit single chip
micro-computer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, capture timer/counter, remote control reception
circuit and other servo systems besides the basic
configurations of 8-bit CPU, ROM, RAM, and I/O
port.
The CXP84120/84124 also provides a power-on
reset function and a sleep/stop function that enables lower power consumption.
