CXP823P24
CMOS 8-bit Single Chip Microcomputer
Description
The CXP823P24 is a highly integrated CMOS 8-bit
single-chip microcomputer which is mainly composed
of an 8-bit CPU, PROM, RAM and I/O ports. This
microcomputer features many other high-performance
circuits in a single-chip CMOS design, including an
A/D converter, serial interface, timer/counter, time-
base timer, capture timer/counter, fluorescent display
tube controller/driver, and remote control receiver.
Also, the CXP823P24 provides the power-on reset
function as well as the sleep/stop function which
assures reduced power consumption.
Being a PROM-incorporated version of the
CXP82324 which has on-chip mask ROM, the
CXP823P24 permits program writing. Therefore, it is
ideally suited for use in system development stage
evaluation and job lot production.
