PCMCIA SRAM Memory Card

SRA Series

SRAM Memory Card

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.

256KB through 8MB

Features

•

High Performance SRAM memory Card

• Single 5 Volt Supply

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