PCMCIA SRAM Memory Card — SRA Series

SRAM MEMORY CARD 256KB THROUGH 8MB

FEATURES

High Performance SRAM memory Card

Single 5 Volt Supply

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

Fast Access times: 150ns

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

– 7 months - type I card

– 18 months - type II card

typical based on 4MB (lower

densities will have greater storage

times)

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

SRA01-SRA04

GENERAL DESCRIPTION

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.

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.

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 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.
