Description

The CXP82940/82948/82952/82960 is a CMOS 8-bit single chip microcomputer integrating on a single

chip an A/D converter, serial interface, timer/counter, time base timer, fluorescent display panel

controller/driver, I2C bus interface, remote control transmission circuit, remote control reception circuit, and 32kHz timer/counter besides the basic configurations of 8-bit CPU, ROM, RAM, and I/O port.
