GENERAL DESCRIPTION
WEDCs Flash memory cards FLF0 Series - offer
high density linear Flash memory for code and data
storage, high performance disk emulation, mobile PC
and embedded applications.
The WEDC FLF0 series is based on Intels 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.
WEDCs FLF0 series cards are built with Intels 64Mb
components, 28F640J5, with manufacturer/device ID
of 89/15H. The FLF0 series is available in standard
densities of 16, 32, 48 and 64MB.
Additionally, WEDCs FLF0 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 FLF0 series
supports densities to 80MB: total of 2 pages: page 0 :=
64MB, page 1 := 16MB.
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 FLF0 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 pinout and mechanical
outline, allowing density upgrades without system
design changes.
WEDCs standard cards are shipped with WEDCs
Flash Logo. Cards are also available with blank
housings (no Logo). The blank housings are available
in both, a recessed (for label) or flat housing. Please
contact WEDC sales representative for further
information on Custom artwork.
