CMOS 16-bit Single Chip Microcomputer
For the availability of this product, please contact the sales office.
Description
The CXP912032 is a CMOS 16-bit micro-computer
integrating on a single chip an A/D converter, serial
interface with an incorporated buffer RAM, high-
precision timing pattern generation function, pulse
cycle measurement circuit, PWM generator, general-
purpose prescaler, vertical sync separation circuit,
and a measurement circuit which measures the
signals of capstan FG, drum FG/PG, reel FG and
other servo systems with high precision, as well as
basic configurations like a 16-bit CPU, ROM, RAM,
and I/O port.
This LSI also provides sleep/stop modes that enable
lower power consumption.
