GENERAL DESCRIPTION
The MSM66573 family of highly functional CMOS 16-bit single chip microcontrollers utilize the nX-8/500S,
Oki's proprietary CPU core.
A wide variety of internal multi-functioned timers provide timer functions such as compare out, capture input,
event counter, auto reload, and PWM, and can be used for periodic and timed measurements.
And 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 MSM66573 family of microprocessors
is optimally suited for the system control of small-sized low power devices.
A three channel serial interface and a high-speed bus interface that has separate address and data buses and does
not require external address latches are provided as interfaces to external devices.
With a 16-bit CPU core that enables high-speed 16-bit arithmetic computations and a variety of bit processing
functions, this general-purpose microcontroller is optimally suited for Digital Audio devices such as a Mini-Disc
and an MP3 player.
The flash ROM version (MSM66Q573LY) programmable with a single 3V power supply (2.7 to 3.3V) and flash
ROM version (MSM66Q573Y) 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.

*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, MSM66Q573LY-999TB.
