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.
