CXP82220/82224
CMOS 8-bit Single Chip Microcomputer
Description
The CXP82220/82224 is a CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, capture timer/counter, fluorescent display tube
controller/driver, remote control reception circuit, CTL
duty detection circuit, 14-bit PWM output, high-speed
output circuit and other servo systems besides the
basic configurations of 8-bit CPU, PROM, RAM, and
I/O port.
The CXP82220/82224 also provides power-on reset
function and sleep/stop function that enables lower
power consumption.

crystal oscillator between TEX and TX. For usage as event input, attach
clock source to TEX, and open TX.
Low-level active, system reset.
NC.
Under normal operation, connect to VDD.
Reference voltage input for A/D converter.
A/D converter GND.
Positive power supply.
