Description

The CXP853P40A are a highly integrated microcomputers composed of a 8-bit CPU, PROM, RAM, and I/O ports. These chips feature many other highperformance circuits in a single-chip CMOS design, including an A/D converter, serial interface, timer/counter, time-base timer, vector interrupt, onscreen display function, I2C bus interface, PWM generator, remote control receiver, HSYNC counter, power supply frequency counter, and watchdog timer.
