Description

The CXP973F064 is a CMOS 16-bit microcomputer integrating on a single chip an A/D converter, serial interface, I2C bus interface, timer, PWM output circuit, programmable pattern generator, remote control receive circuit, parallel interface, FLASH ROM interface, 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.
