Preliminary
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, event
counter, auto reload, and PWM, and can be used for periodic and timed measurements. In addition to the main
clock and clock gear functions, there is a sub clock (32.768 kHz) that is suitable for low power applications. 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 (MSM66Q573L) programmable with a single 2.4 V (minimum) power supply and flash
ROM version (MSM66Q573) programmable with a single 5 V power supply are also included in the family. These
versions are easily adaptable to sudden specification changes and to new product versions.
