The CXP843P40 is a CMOS 8-bit single chip microcomputer that integrates an A/D converter, serial interface, timer/counter, time base timer, capture timer/counter, and remote control reception circuit, in addition to the basic configurations of an 8-bit CPU, ROM, RAM, and I/O port. The CXP843P40 also provides a sleep/stop function for lower power consumption. This IC is the PROM-incorporated version of the CXP84340 with built-in mask ROM, allowing direct writing into the program. It is most suitable for evaluation use during system development and for small-quantity production.
