CXP818P48A
CMOS 8-bit Single Chip Microcomputer
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.
