PCMCIA SRAM MEMORY CARD — SRV SERIES  
SRAM Memory Card 256KB Through 8MB  
FEATURES  
GENERAL DESCRIPTION  
„
High Performance SRAM memory Card  
The WEDC SRAM Series (SRV) memory cards offer a  
high performance nonvolatile storage solution for code  
and data storage, disk caching, and write intensive mobile  
and embedded applications.  
„
Universal 3.3 to 5 Volt Supply allows for wider  
compatibility between systems.  
„
Fast Access times: 150ns @ 5V  
250ns @ 3.3V  
Packaged in PCMCIA type I or type II housing (type II for  
cards with extended battery backup time and 8MB cards),  
the WEDC SRAM SRV 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 SRV series of SRAM memory cards is a universal  
3V/ 5V power supply and operates at speeds as high  
as 150ns. The cards are based on advanced CMOS  
technology providing very low power and reliable data  
retention characteristics. WEDC’s SRAM cards contain  
a rechargeable lithium battery and recharge circuitry,  
eliminating the need for replaceable batteries found in  
many SRAM cards.  
„
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  
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 at housing. Please contact  
WEDC sales representative for further information on  
Custom artwork.  
– 18 months - type II card  
typical based on 4MB (lower  
densities will have greater storage  
times)  
„
„
Unlimited write cycles, no endurance issues  
Optional Features:  
• 2KB EEPROM attribute memory containing CIS  
• Optional Hardware Write Protect switch  
PC Card Standard Type I or Type II Form Factor
