General Description

The A64S9316 is a low operating current 8,388,608-bit Super RAM organized as 524,288 words by 16 bits and operates on low power supply voltage from 2.7V to 3.1V. It is built using AMIC’s high performance CMOS DRAM process.

Using hidden refresh technique, the A64S9316 provides a 100 compatible asynchronous interface.

Inputs and three-state outputs are TTL compatible and allow for direct interfacing with common system bus structures.

The chip enable input is provided for POWER-DOWN, device enable. Two byte enable inputs and an output enable input are included for easy interfacing.

This A64S9316 is suited for low power application such as mobile phone and PDA or other battery-operated handheld device.
