GENERAL DESCRIPTION
The WEDC SEA SRAM Series 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 housing the WEDC SRAM
SEA series is based on 1 or 4Mbit SRAM memories,
providing densities from 128 Kbytes to 512 Kbytes.
The SEA 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 at housing. Please contact
WEDC sales representative for further information on
Custom artwork.
