GENERAL DESCRIPTION  
The Micross Components SRAM family employs  
high-speed, low-power CMOS and are fabricated using double-  
layer metal, double-layer polysilicon technology.  
Military (-55oC to +125oC)

• 2V data retention/low power  
L
For exibility in high-speed memory applications,  
Micross Components offers chip enable (CE\) on all organiza-  
tions. This enhancement can place the outputs in High-Z for  
additional exibility in system design. The x1 conguration  
features separate data input and output.  
*Electrical characteristics identical to those provided for the 45ns  
access devices.  
Writing to these devices is accomplished when write  
enable (WE\) and CE\ inputs are both LOW. Reading is ac-  
complished when WE\ remains HIGH and CE\ goes LOW. The  
device offers a reduced power standby mode when disabled.  
This allows system designs to achieve low standby power  
requirements.

please visit our web site at

These 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 specications without notice.
