PCMCIA Flash Memory Card  
FLD Series  
PCMCIA Flash Memory Card 4 MEGABYTE through 40 MEGABYTE (AMD based)  
General Description  
Features  
Low cost High Density Linear Flash Card  
• Supports 5V only systems  
WEDC’s PCMCIA Flash memory cards offer high  
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.  
•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 FLD series is based on AMD Flash  
memories. The FLD 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 FLD series is designed to support from two to twenty (see Block diagram) 16Mb components, providing a  
wide range of density options. Cards are based on the Am29F017 (16Mb) device for 5V only applications. The  
device code for the Am29F017 is 3Dh and the manufacturer’s ID is 01h. This card is compatible with D series  
cards from AMD. Cards utilizing 16Mb components provide densities ranging from 4MB to 40MB in 4MB  
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 (128kB)blocks. Write, read 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 FLD  
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.
