MSM66579 Family
16-Bit Microcontroller
This version: Nov. 1999
Preliminary
GENERAL DESCRIPTION
The MSM66579 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 bus interface
to correspond to various peripheral LSI devices.
With features such as a clock gear function, dual clock function, programmable pull-up ports in which individual
bits can be programmed, and a small, thin package, the MSM66579 family of microprocessors is optimally suited
for the system control of small-sized low power devices.
The flash ROM versions (MSM66Q577L and MSM66Q579L) programmable with a single 2.7V (minimum)
power supply and flash ROM version (MSM66Q577) programmable with a single 5V power supply are also
included in the family. These versions are easily adaptable to quick specification changes and to new product
revisions.
