GENERAL DESCRIPTION

The MSM66577 family of highly functional CMOS 16-bit single chip microcontrollers utilizes the nX-8/500S, Oki’s proprietary CPU core.

Four channels of serial ports, consisting of two channels of synchronous serial ports with 32-byte FIFO registers and two channels of UART/synchronous serial ports, enable easy interfacing with external peripheral LSI devices such as an encoder/decoder or servocontroller.

A switching function permits selection of separate address and data lines or multiplexed lines for the external bus interface to correspond to various peripheral LSI devices.

With features such as a clock gear function, dual clock function, STOP/HALT mode, programmable pull-up ports in which individual bits can be programmed, and a small, thin package, the MSM66577 family of microprocessors is optimally suited for the system control of small-sized low power devices.
