General Description

The A625308A is a low operating current 262,144-bit static

random access memory organized as 32,768 words by 8

bits and operates on a voltage from 4.5V to 5.5V.

Inputs and three-state outputs are TTL compatible and

allow for direct interfacing with common system bus

structures.

Pin Configurations

„ DIP / SOP

„ Full static operation, no clock or refreshing required

„ All inputs and outputs are directly TTL-compatible

„ Common I/O using three-state output

„ Data retention voltage: 2.0V (min.)

„ Available in 28-pin, DIP/SOP and TSOP

„ Pb-Free package only

„ All Pb-free (Lead-free) products are RoHS compliant

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.
