MSM66573

PEDL66573-02 1 Semiconductor MSM66573 Family 16-Bit Microcontroller This version: Aug. 1999 Previous version: Jun.1999 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.
