Description

The CXP88216/88220/88224 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

circuits, PWM generator, PWM for tuner, VISS/VASS

circuit, 32kHz timer/event counter, remote control

receiving circuit, FDP controller/driver, VCR vertical

sync separation circuit and the measuring 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, CXP88216/88220/88224 provides sleep/stop

function which enables to lower power consumption

and ultra-low speed instruction mode in 32kHz

operation.
