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
