General Description
CXP87540 General Description
The CXP87532/87540 is a CMOS 8-bit microcomputer 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 measures signals of capstan FG, drum FG/PG, reel FG and other servo systems, as well as basic configurations like 8-bit CPU, ROM, 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.
