GENERAL DESCRIPTION
WEDC’s Flash memory cards — FLF1 Series — offer
high density linear Flash memory for code and data
storage, high performance disk emulation, mobile PC and
embedded applications.
The WEDC’s FLF1 series is based on Intel’s Multi Level
Cell (MLC) Flash memory technology, providing high
density Flash components at a signifi cantly 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.
WEDC’s FLF1 series cards are built with Intel’s 128Mb
memory components, 28F128J3A, with a manufacturer/
device ID of 89/18H. The FLF1 series is available in
densities of 32, 64, 96, 128, 160, and 192MB. There are
also 16MB and 48MB cards available built with Intel’s
64Mb memory components 28F640J3 with 89/17H
manufacturer/device ID.
The cards up to the 64MB density operate in the regular
PCMCIA mode. The densities beyond the 64MB density
are implemented using a “paging scheme”, which is also
supported by the PCMCIA standard. By writing a page
address to the Confi guration Option Register (address
4000H), an additional page of memory can be accessed.
The current FLF1 series supports densities up to 192MB:
total of 3 pages: page 0 := 64MB, page 1 := 64MB, and
page 2 := 64MB.
The FLF1 series card operates in a wide, universal
voltage range, from 3V to 5V, allowing full “plug and play”
functionality and upgrade solutions in all mobile, battery
powered applications.
Each memory component in the card also has a 128-
bit Protection Register, containing 64 bits of User
Programmable OTP (One Time Programmable) Cells.
These cells can be programmed with a numeric security
measure, such as an electronic signature.
To provide a 16 bit word wide access supported by
the 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 FLF1 series cards conform to 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.
WEDC’s standard cards are shipped with WEDC’s Flash
Logo. Cards are also available with blank housings
(no Logo). The blank housings are available in both, a
recessed (for label) or fl at housing. Please contact your
WEDC sales representative for further information on
