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.

Description
Provides voltage for FDP.
Connection for system clock oscillation crystal. When using an external
clock, input normal signal to EXTAL and reverse phase signal to the
XTAL pin.
System reset, active "L". The RST pin is an input/output pin which
outputs a "L" level from the on-chip power on reset circuit when the
power is turned on.
Positive power supply for the programmable on-chip PROM; connect to
VDD for nomal operation.
Positive power supply pin.
