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.
