CXP853P40A
CMOS 8-bit Single-chip Microcomputer
Description
The CXP853P40A are a highly integrated micro-
computers composed of a 8-bit CPU, PROM, RAM,
and I/O ports. These chips feature 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 CXP853P40A is the one-chip PROM version
of the CXP85340A 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.
64 pin SDIP (PIastic)
