PCMCIA Flash Memory Card
FLF10 Series
High Density FLASH Memory Card
General Description
WEDC鈥檚 Flash memory cards - FLF10 Series - offer high density
linear Flash memory for code and data storage, high performance
disk emulation, mobile PC and embedded applications.
The WEDC FLF10 series is based on Intel鈥檚 Multi Level Cell
(MLC) Flash memory technology, providing high density Flash
components at a 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.
WEDC鈥檚 FLF10 series cards are built with Intel鈥檚 128Mb memory
component, 28F128J3A, with a manufacturer/device ID of 89/18
H
.
The FLF10 series is available in densities of 32, 64, 96, 128, 160,
and 192MB.
WEDC鈥檚 FLF10 series provides densities from 32MB to 192MB, in
32MB increments. The cards up to the 64MB density operate in the
regular PCMCIA mode. The densities beyond the 64MB density
are implemented using a 鈥減aging scheme鈥? which is also supported
by the PCMCIA standard. By writing a page address to the
Configuration Option Register (address 4000H), an additional page
of memory can be accessed. The current FLF10 series supports
densities to 192MB: total of 3 pages: page 0 := 64MB, page 1 :=
64MB, and page 2 := 64MB.
The FLF10 series card operates in a wide, universal voltage range,
from 3V to 5V, allowing full 鈥減lug and play鈥?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 FLF10 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鈥檚 standard cards are shipped with WEDC鈥檚 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.
