CXP872P48A
CMOS 8-bit Single Chip Microcomputer
Description
The CXP872P48A 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, VISS/VASS circuit, 32kHz
timer/event counter, remote control receiving circuit,
general purpose prescaler, HSYNC counter, VCR
vertical sync separation circuit and the measuring
circuit which measure signals of capstan FG and
drum FG/PG and other servo systems, as well as
basic configurations like 8-bit CPU, PROM, RAM and
I/O port. They are integrated into a single chip.
Also this IC provides sleep/stop function which
enables to lower power consumption and ultra-low
speed instruction mode in 32kHz operation.
The CXP872P48A is the on-chip PROM version of
the CXP87248A with on-chip mask ROM, providing
the function of being able to write directly into the
program. It is suitable for evaluation use during
system development and for small quantity production.
