CXP85324A/85332A/85340A
CMOS 8-bit Single Chip Microcomputer
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, I
2
C 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.
