PCMCIA SRAM Memory Card

SRA Series

SRAM Memory Card 256KB through 8MB

General Description

Features

• High Performance SRAM memory Card

The WEDC SRAM Series (SRA) memory cards offer a

high performance nonvolatile storage solution for code

and data storage, disk caching, and write intensive

mobile and embedded applications.

• Single 5 Volt Supply

- (3.3V/5V operation is available as an option)

• Fast Access times: 150ns

Packaged in PCMCIA type I or type II housing (type II

for cards with extended battery backup time), the

WEDC SRAM SRA 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 SRA series of SRAM memory cards requires a 5V

power supply and operates at speeds to 150ns. The

cards are based on advanced CMOS technology

providing very low power and reliable data retention

• 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

characteristics. WEDC’s SRAM cards contain

•18 months - type II card

rechargeable lithium battery and recharge circuitry,

eliminating the need for replaceable batteries found in

many SRAM cards.

typical based on 4MB (lower densities will

have greater storage times)

• Unlimited write cycles, no endurance issues

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.

• Optional Features:

• 2KB EEPROM attribute memory containing

CIS

• Optional Hardware Write Protect switch

• PC Card Standard Type I or Type II Form Factor
