Description

The CXP852P32A is highly integrated microcomputers composed of 8-bit CPU, PROM, RAM, and I/O ports. This IC featureS 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 CXP852P32A is the on-chip PROM version of the CXP85232A 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.
