Description
The CXP921F064A is a CMOS 16-bit microcomputer
integrating on a single chip an A/D converter, serial
interface, I
2
C bus interface, timer, 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.
Features
An efficient instruction set as a controller
— Direct addressing, numerous abbreviated forms,
multiplication and division instructions
Instruction sets for C language and RTOS
— Highly quadratic instruction system, general-
purpose register of 16-bit
