General Description

The A623308 is a low operating current 65,536-bit static

random access memory organized as 8,192 words by 8

bits and operates on a single 5V power supply.

Inputs and three-state outputs are TTL compatible and

allow for direct interfacing with common system bus

structures.

Minimum standby power is drawn by this device when

CE is at a high level, independent of the other input

levels.

Data retention is guaranteed at a power supply voltage

as low as 2.0V.

Notes: 1. tAS is measured from the address valid to the beginning of Write.

2. A Write occurs during the overlap (tWP) of a low CE and a low WE.

3. tWR is measured from the earliest of CE or WE going high to the end of the Write cycle.

4. If the CE low transition occurs simultaneously with the WE low transition or after the WE transition, outputs

remain in a high impedance state.

5. tCW is measured from the later of CE going low to the end of Write.

6. OE level is high or low.

7. Transition is measured ±500mV from steady. This parameter is sampled and not 100% tested.
