CXP80732A/80740A
CMOS 8-bit Single Chip Microcomputer
Description
100 pin QFP (PIastic)
100 pin LQFP (PIastic)
The CXP80732A/80740A is a CMOS 8-bit micro-
computer 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, 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.
Structure
Silicon gate CMOS IC
Also CXP80732A/80740A provides sleep/stop function
which enables to lower power consumption and ultra-
low speed instruction mode in 32kHz operation.
