CXP871P40

CMOS 8-bit Single Chip Microcomputer

Description

The CXP871P40 is a CMOS 8-bit microcomputer

which consists of A/D converter, serial interface (2ch

independently), timer/counter, time base timer,

vector interruption, high precision timing pattern

generation circuit (PPG 2ch independently, RTG 2ch

independently), PWM generator, general purpose

prescaler, PWM for tuner, VCR vertical sync

separation circuit and the measuring circuit which

measures signals of capstan FG and drum FG/PG

and other servo systems, as well as basic

configurations like 8-bit CPU, PROM, RAM and I/O

port. They are integrated into a single chip.

100 pin QFP (PIastic)

100 pin LQFP (PIastic)

Also CXP871P40 provides power on reset

function, sleep/stop function which enables to lower

power consumption .

CXP871P40 is the PROM-incorporated version of

the CXP87132/87140 with built-in mask ROM. This

provides the additional feature of being able to write

directly into the program. Thus, it is most suitable for

evaluation use during system development and for

small-quantity production.
