GENERAL DESCRIPTION
No. 106
E C
The Micross Components SRAM family employs high-
speed, low-power CMOS designs using a four-transistor mem-
ory cell. Austin Semiconductor SRAMs are fabricated using
double-layer metal, double-layer polysilicon technology.
For flexibility in high-speed memory applications, Micross
Components offers chip enable (CE\) and output enable (OE\)
capability. These enhancements can place the outputs in High-Z
for additional flexibility in system design.

Military (-55oC to +125oC)

• 2V data retention/low power
L
*Electrical characteristics identical to those provided for the 35ns ac-
cess devices.
Writing to these devices is accomplished when write enable
(WE\) and CE\ inputs are both LOW. Reading is accomplished
when WE\ remains HIGH and CE\ and OE\ go LOW. The
device offers a reduced power standby mode when disabled.
This allows system designs to achieve low standby power
requirements.

All devices operate from a single +5V power supply and all
inputs and outputs are fully TTL compatible.
Micross Components reserves the right to change products or specifications without notice.
