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.
