DescriptionThe CXP871P40 is a CMOS 8-bit microcomputer which consists of A/D converter, serial interface (2chindependently), timer/counter, time base timer,vector interruption, high precision timing pattern generation circuit (PPG 2ch independently, RTG 2chindependently), PWM generator,general purpose prescaler, PWM for tuner, VCR vertical sync separation circuit and the measuring circuit which measures 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 CXP871P40 provides power on reset function, sleep/stop function which enables to lower
power consumption .
CXP871P40 is the PROM-incorporated version of the CXP87132/87140 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.
