CXP822P24
CMOS 8-bit Single Chip Microcomputer
Description
The CXP822P24 is a CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, capture timer counter, fluorescent display tube
controller/driver, remote control reception circuit, CTL
duty detection circuit, 14-bit PWM output and high-
speed output circuit besides the basic configurations
of 8-bit CPU, PROM, RAM, and I/O port.
The CXP822P24 also provides sleep/stop function
that enables lower power consumption.
CXP822P24 is the PROM-incorporated version of
the CXP82224 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 producton.
