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 highspeed 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.
