PCMCIA SRAM Memory Card — SRA Series

SRAM MEMORY CARD 256KB THROUGH 8MB

FEATURES

GENERAL DESCRIPTION

ꢀ

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 SRAseries 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

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.

• 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

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.

– 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
