Description

The CXP81952/81960 is a CMOS 8-bit microcomputer which consists of A/D converter, serial interface, timer/counter, time base timer, vector interruption, high precision timing pattern generation circuit, PWM generator, PWM for tuner, 32kHz timer/event counter, remote control receiving circuit,general purpose prescaler, and external signal, as well as basic configurations like 8-bit CPU, ROM,RAM and I/O port. They are integrated into a single chip.
Also the CXP81952/81960 provides sleep/stop function which enables to lower power consumption and ultra-low speed instruction mode in 32kHz operation.
