Description

The CXP877P48A 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, 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 CXP877P48A provides sleep/stop function which enables to lower power consumption and ultra low speed instruction mode in 32kHz operation.
This IC is the PROM-incorporated version of the CXP87748A with built-in mask ROM. This provides the additional feature of being able to write directly into the program. Thus, it is most suitable for evaluation use during system development and for small-quantity production.
