CXP875P40
CMOS 8-bit Single Chip Microcomputer
Description
The CXP875P40 is a CMOS 8-bit micro-computer
which consists of arithmetic coprocessor, A/D
converter, serial interface, timer/counter, time base
timer, vector interruption, high precision timing
pattern generation circuit, PWM generator and the
measuring circuit which measure signals of capstan
FG, drum FG/PG, reel FG 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 this IC provides power on reset function,
sleep/stop function which enables to lower power
consumption.
The CXP875P40 is the one-chip PROM version of
the CXP87532/87540 with mask ROM, providing the
function of being able to write directly into the
program. It is suitable for evaluation use during
system development and for small quantity
production.
