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 fl at housing. Please contact
WEDC sales representative for further information on
Custom artwork.
