PCMCIA Flash Memory Card  
FLG Series  
White Electronic Designs  
PCMCIA Flash Memory Card - 256 KILOBYTE through  
5 MEGABYTE (Intel/Catalyst based)  
GENERAL DESCRIPTION  
ARCHITECTURE OVERVIEW  
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.  
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.  
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 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.  
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.  
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/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.  
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.
