Description
The CXP81720B/81724B is a CMOS 8-bit microcomputer which consists of A/D converter, serial interface, timer/counter, time-base timer, high precision timing pattern generation circuit, PWM output, 32kHz timer/counter, remote control reception circuit, as well as basic configurations like 8-bit CPU, ROM, RAM and I/O port. They are integrated into a single chip.
Also CXP81720B/81724B provides sleep/stop functions which enables to lower power consumption.
