GENERAL DESCRIPTION
This version: Jan. 1998 MSM6577-xx Previous version: Mar. 1996
Operatable at 0.9V and Built-in LCD Driver 4-Bit Microcontroller
The MSM6577 is a 4-bit microcontroller that is fabricated in OKI's low-voltage CMOS technology, enabling operation at 0.9 V. This device incorporates LCD drivers, 8-bit synchronous serial ports, and a buzzer output circuit. The MSM6577 is optimized for remote-control microcontroller applications that are portable and battery powered.
