The CXP87352/87360 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, general purpose prescaler, HSYNC
counter, VCR vertical sync separation circuit and the
measurement circuit which measure 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 CXP87352/87360 provides sleep/stop
function which enables to lower power consumption
and ultra-low speed instruction mode in 32kHz
operation.
