It is designed to be compatible with all microprocessors and similar applications where high-performance, large-bit storage, and simple interfacing are important design considerations. This device is designed for use with operating voltage from 3V to 5V. The A23W8308 offers an automatic POWER-DOWN controlled by the Chip Enable CE/ CE input. When CE/ CE goes low/high, the device will automatically POWER-DOWN and remain in a low power STANDBY mode as long as CE/ CE remains low/high. A23W8308 also offers OE/ OE /NC (Active High or Low or No Connection), which eliminates bus contention in multiple bus microprocessor systems.
