Description

The CXP82832/82840/82852/82860 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

panel

controller/driver,

remote

control

reception circuit, and PWM output besides the basic

configurations of 8-bit CPU, ROM, RAM, and I/O port.

The CXP82832/82840/82852/82860 also provides

sleep/stop

function

that

enables

lower

power

consumption.
