Description
The CXP84412/84416 is a CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, 32kHz 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 CXP84412/84416 also provides and a sleep/
stop function that enables lower power consumption.
