DescriptionThe CXP87852/87860 is a CMOS 8-bit microcomputer which consists of A/D converter, serial interface, timer/counter, time base timer, high precision timing
pattern generation circuit, PWM output, VISS/VASS circuit, 32kHz timer/counter, remote control reception circuit, HSYNC counter, VSYNC separator and the measurement circuit which measures signals of capstan FG and drum FG/PG 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 the CXP87852/87860 provides sleep/stop unctions which enable to lower power consumption.
