PCMCIA SRAM Memory Card  
SRA Series  
SRAM Memory Card 256KB through 8MB  
General Description  
Features  
• High Performance SRAM memory Card  
The WEDC SRAM Series (SRA) memory cards offer a  
high performance nonvolatile storage solution for code  
and data storage, disk caching, and write intensive  
mobile and embedded applications.  
• Single 5 Volt Supply  
- (3.3V/5V operation is available as an option)  
• Fast Access times: 150ns  
Packaged in PCMCIA type I or type II housing (type II  
for cards with extended battery backup time), the  
WEDC SRAM SRA series is based on 1 or 4Mbit  
SRAM memories, providing densities from 256  
Kilobytes to 8 Megabytes.  
• x8/x16 PCMCIA standard interface  
• Low Power CMOS technology provides very low  
power and reliable data retention characteristics  
- standby current < 100µA typical  
The SRA series of SRAM memory cards requires a 5V  
power supply and operates at speeds to 150ns. The  
cards are based on advanced CMOS technology  
providing very low power and reliable data retention  
• Rechargeable Lithium battery with recharge circuitry  
- eliminates the need for replaceable batteries  
- standby current during recharge typically < 2mA  
- battery backup time  
•7 months - type I card  
characteristics. WEDC’s SRAM cards contain  
a
•18 months - type II card  
rechargeable lithium battery and recharge circuitry,  
eliminating the need for replaceable batteries found in  
many SRAM cards.  
typical based on 4MB (lower densities will  
have greater storage times)  
• Unlimited write cycles, no endurance issues  
WEDC’s standard cards are shipped with WEDC’s  
SRAM Logo. Cards are also available with blank  
housings (no Logo). The blank housings are available  
in both a recessed (for label) and flat housing. Please  
contact WEDC sales representative for further  
information on Custom artwork.  
• Optional Features:  
• 2KB EEPROM attribute memory containing  
CIS  
• Optional Hardware Write Protect switch  
• PC Card Standard Type I or Type II Form Factor
