CXP88216/88220/88224
CMOS 8-bit Single Chip Microcomputer
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.
