PCMCIA Flash Memory Card
FLG Series
PCMCIA Flash Memory Card
General Description
WEDC鈥檚 FLG Series Flash memory cards offer low/medium
density linear Flash solid state storage solutions for code and
data storage, high performance disk emulation and execute in
place (XIP) applications in mobile PC and dedicated
(embedded) equipment.
FLG series cards conform to PCMCIA international standard.
The card鈥檚 control logic provides the system interface and
controls the internal Flash memories. Card can be
read/written in byte-wide or word-wide mode which allows
for flexible integration into various systems. Combined with
file management software, such as Flash Translation Layer
(FTL), FLG Flash cards provide removable high-performance
disk emulation.
The FLG series cards contain separate 2kB EEPROM
memory for Card Information Structure (CIS) which can be
used for easy identification of card characteristics.
The WEDC FLG series is based on Intel 28F010 or 28F020
Flash memories.
Note: Standard options include attribute memory. Cards
without attribute memory are available. Cards are also
available with or without a hardware write protect switch.

Architecture Overview
WEDC鈥檚 FLG series is designed to support from 2 to 20, 1Mb or 2MB components, providing a wide range of
density options. Cards are based on the 28F010 (1Mb) or 28F020 components which work with 5V Vcc / 12V Vpp
applications. Device codes are
B4h
and
BDh
respectively. Systems should be able to recognize both codes. Cards
utilizing the1Mb components provide densities ranging from 256KB to 2.5MB in 256KB increments, cards utilizing
2Mb components provide densities ranging from 512KB to 5MB in 512KB increments.
In support of the PC Card 95 standard for word wide access devices are paired. Write, read and erase operations can
be performed as either a word or byte wide operation . By multiplexing A0, CE1# and CE2#, 8-bit hosts can access
all data on data lines DQ0 - DQ7. The FLG series cards conform to the PC Card Standard (PCMCIA) and JEIDA,
providing electrical and physical compatibility. The PC Card form factor offers an industry standard pinout and
mechanical outline, allowing density upgrades without system design changes.
WEDC鈥檚 standard cards are shipped with WEDC鈥檚 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.
