Description
The CXP83120A/83124A is a CMOS 8-bit single chip microcomputer integrating on a single chip an A/D converter, serial interface, timer/counter, time base timer, 32kHz timer/counter, capture timer counter, LCD controller/driver, remote control reception circuit and 14-bit PWM output besides the basic configurations of 8-bit CPU, ROM, RAM, and I/O port.
The CXP83120A/83124A also provides a sleep/stop function that enables lower power consumption.
