MSM66Q577

PEDL66577-01 Semiconductor 1 MSM66577 Family 16-Bit Microcontroller This version: Apr. 2000 Preliminary 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. The flash ROM version (MSM66Q577LY) programmable with a single 3V power supply (3.0 to 3.6V) and flash ROM version (MSM66Q577) programmable with a single 5V power supply (4.5 to 5.5V) are also included in the family. These versions are easily adaptable to sudden specification changes and to new product versions.
