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.

MSM66Q577-NTB *2
MSM66577 flash ROM version (4.5 to 5.5 V)
*1 : The “xx” of “-xx” stands for the code number.
*2 : The “N” of “-N” stands for the flash ROM and the OTP ROM, blank version.
When OKI programs and ship the flash ROM and OTP, the part number is changed from ”–N” to ”–XX” (code
number ) , for example, MSM66Q577-999TB.
