CMOS 8-bit Single Chip Microcomputer
Description
CXP84332/84340 is a CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, capture timer/counter, remote control reception
circuit, and the like besides the basic configurations of
8-bit CPU, ROM, RAM, and I/O port.
The CXP84332/84340 also provides a power-on
reset function and a sleep/stop function that enables
lower power consumption.
