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.

Also, this IC provides power-on reset and sleep functions. The designers have ensured low power consumption for these powerful microcomputers.

The CXP853P40A is the one-chip PROM version of the CXP85340A with on-chip mask ROM, providing the function of being able to write directly into the program. Furthermore, because of the OSD character ROM can also be written directly into, it is suitable for evaluation use during system development and for small quantity production.
