CXP80724B

CMOS 8-bit Single Chip Microcomputer

Sony Semiconductor 

CXP80712B/80716B/80720B/80724B

CMOS 8-bit Single Chip Microcomputer

Description

The CXP80712B/80716B/80720B/80724B 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 receiving circuit, 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 CXP80712B/80716B/80720B/80724B provides

sleep/stop function which enables to lower power

consumption.
