PCMCIA SRAM Memory Card

SRV20 Series

SRAM Memory Card 2MB through 16MB

General Description

Features

• High Performance SRAM memory Card

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.

• 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

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.

• 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

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.

typical based on 4MB

• Unlimited write cycles, no endurance issues

• Optional Features:

• 2KB EEPROM attribute memory containing CIS

• Optional Hardware Write Protect switch

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.
