PEDL66577-01
Semiconductor

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鈥檚 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.
