Description

The CXP861P16 is a highly integrated CMOS 8-bit single-chip microcomputer which is mainly composed of an 8-bit CPU, PROM, RAM and I/O ports. This microcomputer features many other highperformance circuits in a single-chip CMOS design, including an A/D converter, clock synchronized serial interface, UART, stepping motor controller, PWM generator, 16-bit timer/counter, and watchdog timer.
Also, the CXP861P16 provides the power-on reset function as well as the sleep/stop function which enables to lower power consumption.
This IC is the PROM-incorporated version of the CXP86116 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 smallquantity production.
