WEDC PCMCIA SRV30 SERIES SRAM MEMORY CARD 

SRAM Memory Card 2 MB Through 16 MB

SRAM memory cards offer high-performance nonvolatile storage solutions for code and data storage, disk caching, and write intensive mobile and embedded applications. They require a 3V or 5V power supply and operate at access times of 150ns. These SRAM cards are based on advanced CMOS technology providing very low power and reliable data retention characteristics.

Our SRAM cards contain a rechargeable lithium battery and recharge circuitry, thus eliminating the need for replacement batteries found in many SRAM cards. Typical data retention time, without recharging, is 1 year for a 2MB card. The minimum battery life is 10 years. All our SRAM cards are built in welded stainless steel housings to ensure card integrity and data retention.
