Description
The CXP85324A/85332A/85340A are a highly integrated microcomputers composed of a 8-bit CPU, ROM, RAM, and I/O ports. These chips feature many other high-performance circuits in a single-chip CMOS design, including an A/D converter, serial interface, timer/counter, time-base timer, on-screen display function, I2C bus interface, PWM output, remote control reception circuit, HSYNC counter, power supply frequency counter, and watchdog timer.
Futhermore, the CXP85324A/85332A/85340A series provides power-on reset and sleep functions which enable to lower power consumption.
