					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.

					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 flat housing. Please contact  
					WEDC sales representative for further information on  
					Custom artwork.
