Description

The CXP818P48A is a CMOS 8-bit microcomputer

which consists of A/D converter, serial interface,

timer/counter, time base timer, vector interruption,

high precision timing pattern generation circuit, PWM

generator,

PWM

for

tuner,

32kHz

timer/event

counter, remote control receiving circuit, as well as

basic configurations like 8-bit CPU, PROM, RAM

and I/O port. They are integrated into a single chip.

Also CXP818P48A provides sleep/stop function

which enables to lower power consumption and ultra

low speed instruction mode in 32kHz operation.

This IC is the PROM-incorporated version of the

CXP81848A with built-in mask ROM. This provides

the additional feature of being able to write directly

into the program. Thus, it is most suitable for

evaluation use during system development and for

small-quantity production.
