PCMCIA Flash Memory Card  
FLF Series  
High Density FLASH Memory Card 16, 32, 48, 64, 80 MEGABYTE  
General Description  
Features  
Low cost, high density Linear Flash Card  
WEDC’s Flash memory cards - FLF Series - offer  
high density linear Flash memory for code and data  
storage, high performance disk emulation, mobile PC  
and embedded applications.  
• Single 5V Supply  
- (3V/5V operation is available as option)  
• Based on Intel 28F640J5 (MLC) Components  
The WEDC FLF series is based on Intel’s Multi Level  
Cell (MLC) Flash memory technology, providing  
high density Flash components at significantly lower  
cost per megabyte. MLC technology allows for two  
bits of information to be stored in a single cell. This  
leads to reduced die size and reduced cost per  
megabyte.  
• Fast Read Performance  
- 250ns Maximum Access Time  
- (200ns optional)  
•PCMCIA compatible  
- x8/ x16 Data Interface  
• 32-Byte Write Buffer  
WEDC’s FLF series cards are built with Intel’s 64Mb  
components, 28F640J5, with manufacturer/device ID  
of 89/15H. The FLF series is available in standard  
densities of 16, 32, 48 and 64MB.  
- 6µs per Byte Effective Write Time  
• Cross-Compatible Command Support  
- Intel Basic Command Set  
- Common Flash Interface (CFI)  
- Scaleable Command Set  
Additionally, WEDC’s FLF series provides densities  
beyond the 64MB density, supported by PCMCIA  
standard. These higher densities are based on a  
“paging scheme”. By writing a page address to the  
Configuration Option Register (address 4000H), an  
additional page of memory could be access. The  
current FLF series supports densities to 80MB: total  
of 2 pages: page 0 := 64MB, page 1 := 16MB.  
• Power-Down Mode  
- Reset, Power Down Registers  
• 10,000 Erase Cycles per Block  
• 128K word symmetrical Block Architecture  
• PC Card Standard Type II Form Factor  
To provide a 16 bit word wide access and to support  
PCMCIA standard, devices are paired on the card.  
Therefore, the Flash array is structured in 128K word  
(256kB) blocks. Write, read and block erase  
operations can be performed as either a word or byte  
wide operation.

The FLF series cards conform with the PC Card 95  
Standard supported by PCMCIA and JEIDA,  
providing electrical and physical compatibility. The  
PC Card form factor offers an industry standard
