Overview

CXP85452/85460 CMOS 8-bit Single Chip Microcomputer Description The CXP85452/85460 are a highly integrated microcomputers composed of a 8-bit CPU, ROM, 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, on-screen display function, I2C bus interface, PWM output, remote control reception circuit, HSYNC counter, and watchdog timer.
Futhermore, the CXP85452/85460 series provides power-on reset and sleep functions which enable to lower power consumption.
