CXP85452/85460
CMOS 8-bit Single Chip Microcomputer
Description
The CXP85452/85460 are a highly integrated micro-
computers 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, and
watchdog timer.
Futhermore, the CXP85452/85460 series provides
power-on reset and sleep functions which enable to
lower power consumption.
