DescriptionThe CXP875P40 is a CMOS 8-bit micro-computer which consists of arithmetic coprocessor, A/D converter, serial interface, timer/counter, time base timer, vector interruption, high precision timing pattern generation circuit, PWM generator and the measuring circuit which measure signals of capstan FG, drum FG/PG, reel FG 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 power on reset function, sleep/stop function which enables to lower power consumption.
The CXP875P40 is the one-chip PROM version of the CXP87532/87540 with 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.
