The CXP847P60 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, FRC capture unit, highprecision timing pattern generation circuit, PWM output, and the like besides the basic configurations of 8-bit CPU, PROM, RAM, and I/O ports. The CXP847P60 also provides the sleep/stop functions that enable to execute the power-on reset function and lower the power consumption. The CXP847P60 is the PROM-incorporated version of the CXP84716/84720/84724 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 evaluaiton use during system development and for small-quantity production.
