PCMCIA SRAM Memory Card
SRV20 Series
SRAM Memory Card
General Description
2MB through 16MB
Features
High Performance SRAM memory Card
• Universal 3.3 to 5 Volt Supply allows for wider
compatibility between systems.
• Fast Access times: 150ns @ 3.3V – 5V
• x8/x16 PCMCIA standard interface
• Low Power CMOS technology provides very low
power and reliable data retention characteristics
- standby current < 100µA typical
• Rechargeable Lithium battery with recharge circuitry
- eliminates the need for replaceable batteries
- standby current during recharge typically < 2mA
- battery backup time
• 18 months - type I card
• 40 months - type II card
typical based on 4MB
• 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
The WEDC SRAM Series (SRV20) memory cards
offer a high performance nonvolatile storage solution
for code and data storage, disk caching, and write
intensive mobile and embedded applications.
Packaged in PCMCIA type I or type II housing (type
II for cards with extended battery backup time), the
WEDC SRAM SRV20 series is based on high
density and super low power SRAM memory
devices, providing densities from 2MBytes to
16MBytes.
The SRV20 series of SRAM memory cards has a
universal wide power supply (3V to 5V) 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.
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.
