Description

The CXP841P24 is a CMOS 8-bit microcomputer integrating on a single chip an A/D converter, serial interface, timer/counter, time base timer, capture timer/counter, and remote control reception circuit besides the basic configurations of 8-bit CPU, ROM, RAM, and I/O port.
The CXP841P24 also provides a sleep/stop function that enables lower power consumption.
This IC is the PROM-incorporated version of the CXP84124 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.
