Description

The CXP84640 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, I²C bus interface, remote control reception circuit, PWM output, and 32kHz timer/counter besides the basic configurations of 8-bit CPU, ROM, RAM, and I/O port.
The CXP84640 also provides a sleep/stop function that enables lower power consumption.
