Preliminary
A625308A Series
32K X 8 BIT CMOS SRAM
Features
n Power Supply Range: 4.5V to 5.5V
n Access times: 70 ns
A625308A-S series: Operating: 35mA (max.)
Standby: 10µA (max.)

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.

n Extended operating temperature range: 0°C to 70°C
for -S series, -25°C to 85°C for -SI series, -40°C to
85°C for -SU series.
n Full static operation, no clock or refreshing required
n All inputs and outputs are directly TTL-compatible
n Common I/O using three-state output
n Data retention voltage: 2.0V (min.)
n Available in 28-pin, DIP/SOP and TSOP
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.
