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.
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.
