CXP921064A
CMOS 16-bit Single Chip Microcomputer
Description
The CXP921064A is a CMOS 16-bit microcomputer
integrating on a single chip an A/D converter, serial
interface, I
2
C bus interface, timer, real-time pulse
generator, clock prescaler, remote control receive
circuit, and as well as basic configurations like a 16-
bit CPU, ROM, RAM, and I/O port.
This LSI also provides the sleep/stop functions that
enable lower power consumption.
