CXP824P40A
CMOS 8-bit Single Chip Microcomputer
Description
The CXP824P40A 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 CXP824P40A also provides sleep/stop function
that enables lower power consumption.
CXP824P40A is the PROM-incorporated version of
the CXP82440A 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.
