PCMCIA Flash Memory Card - 256 KILOBYTE through
5 MEGABYTE (Intel/Catalyst based)
GENERAL DESCRIPTION
WEDC’s 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’s 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 exible integration into various systems. Combined
with le 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 identication of card characteristics.
The WEDC FLG series is based on Intel/Catalyst 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.
FEATURES

100,000 Erase/Program Cycles
PC Card Standard Type I Form Factor
ARCHITECTURE OVERVIEW
WEDC’s 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
(Manufacture ID
89 for Intel and 31 for Catalyst). Systems
should be able to recognize all the 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’s standard cards are shipped with WEDC’s 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.
