CXP832P40A
CMOS 8-bit Single Chip Microcomputer
Description
The CXP832P40A is a CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, 32kHz timer/counter, capture timer counter,
LCD controller/driver, remote control reception
circuit and 14-bit PWM output besides the basic
configurations of 8-bit CPU, PROM, RAM, and I/O port.
Also the CXP832P40A provides sleep/stop function
which enables to lower power consumption.
The CXP832P40A is the PROM-incorporated
version of the CXP83240A with built-in mask ROM.
This provides the additional feature of being able to
write directry into the program. Thus, it is most
suitable for evaluation use during system
development and for small-quantity production.
