The MSM66579 Family including MSM66576, MSM66577, MSM66578, MSM66579, MSM66Q577 (Flash ROM) and MSM66Q579 (Flash ROM) is OKI's original high-performance, CMOS 16-Bit single-chip microcontroller family.The MSM66579 Family is equipped with powerful serial ports which are capable of communication with various external devices:
•Êsynchronous with 32 byte FIFO x 2
• synchronous / UART switchable x 2
Also the 12KByte RAM version of the MSM66579 Family (MSM66578, MSM66579 and MSM66Q579) offers many capabilities for various kinds of applications requiring large RAM size. A sub clock oscillator (32.768kHz) allows delicate power management. Bit programmable pull-up ports reduce external parts count, while the small and thin package saves system space. Therefore, the MSM66579 family is suitable for control tasks in portable systems.MSM66Q577 and MSM66Q579 Flash ROM versions of the MSM66579 Family can be programmed by a +2.7V single power supply. Therefore, MSM66Q577 and MSM66Q579 can be programmed on the application system board allowing for quick specification changes and upgrading.
