CXP852P32A
CMOS 8-bit Single-chip Microcomputer
Description
The CXP852P32A is highly integrated micro-
computers composed of 8-bit CPU, PROM, RAM,
and I/O ports. This IC featureS many other high-
performance circuits in a single-chip CMOS design,
including an A/D converter, serial interface,
timer/counter, time base timer, vector interrupt, on-
screen display function, I
2
C bus interface, PWM
generator, remote control receiver, HSYNC counter,
power supply frequency counter, and watchdog
timer.
Also this IC provides power-on reset and sleep
functions. The designers have ensured low power
consumption for these powerful microcomputers.
The CXP852P32A is the on-chip PROM version of
the CXP85232A with on-chip mask ROM, providing
the function of being able to write directly into the
program. Furthermore, because of the OSD
character ROM can also be written directly into, it is
suitable for evaluation use during system development
and for small quantity production.
