PCMCIA Flash Memory Card  
FLE Series  
PCMCIA Flash Memory Card  
General Description  
8 MEGABYTE through 64 MEGABYTE (AMD based)  
Features  
WEDC’s PCMCIA Flash memory cards offer the  
highest 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.  
Very High Density Linear Flash Card  
• Supports 5V only systems  
•Based on AMD Flash Components  
-low standby power without entering reset mode  
-allows standard access from standby mode  
Packaged in a PCMCIA type I housing, each card  
contains a connector, an array of Flash memories  
packaged in TSOP packages and card control logic.  
The card control logic provides the system interface  
and controls the internal Flash memories. Combined  
with file management software, such as Flash  
Translation Layer (FTL), WEDC Flash cards provide  
removable high-performance disk emulation.  
•Fast Read Performance  
- 150ns Maximum Access Time  
• x8/ x16 Data Interface  
• High Performance Random Writes  
- 7µs Typical Word Write Time  
• Automated Write and Erase Algorithms  
- AMD Command Set  
The WEDC FLE series is based on AMD Flash  
memories. The FLE series offers byte wide and word  
wide operation, low power modes and Card  
Information Structure (CIS) for easy identification of  
card characteristics.  
• 1,000,000 Erase Cycles per Block  
• 64K word (128kB) symmetrical Block Architecture  
• PC Card Standard Type I Form Factor  
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’s FLE series is designed to support up to twenty (see Block diagram) 32Mb components, providing a wide  
range of density options. Cards are based on the Am29F032 (32Mb) device for 5V only applications. The device  
code for the Am29F032 is 41h and the manufacturer’s ID is 01h. Systems should be able to recognize these codes.  
Cards utilizing 32Mb components provide densities ranging from 8MB to 64MB in 8MB increments.  
In support of the PC Card (PCMCIA) standard for word wide access, devices are paired. Therefore, the Flash array  
is structured in 64K word blocks. Write, read and block 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  
FLE series cards conform with the PC Card Standard (formerly PCMCIA) and supported 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 silkscreen design. Cards are also available with blank housings  
(no silkscreen). The blank housings are available in both a recessed (for label) and flat housing. Please contact your  
WEDC sales representative for further information on Custom artwork.
