GENERAL DESCRIPTION
The WEDC SRAM Series (SRV) 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 and 8MB cards),
the WEDC SRAM SRV series is based on 1 or 4Mbit
SRAM memories, providing densities from 256 Kilobytes
to 8 Megabytes.
The SRV series of SRAM memory cards is a universal
3V/ 5V power supply and operates at speeds as high
as 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
at housing. Please contact
WEDC sales representative for further information on
Custom artwork.
