Description

The CXR702F080 is a CMOS 32-bit microcomputer integrating on a single chip an A/D converter, serial interface, timer, bus interface unit, DMA controller, memory stick interface, and as well as basic configurations like a 32-bit RISC CPU, ROM, RAM, and I/O port.

This also provides the idle/sleep/stop functions that enable lower power consumption.
