PC Card Standard Type I Form Factor
The WEDC Value Series (FV) Flash memory cards
offers a low cost linear Flash solid state storage
solution for code and data storage, high performance
disk
emulation,
mobile
applications.
PC
and
embedded
The WEDC Value series is based on Intel/Sharp Flash
memories. Cards are based on the 28F008SA (8Mb),
28F008S5 (8Mb) or 28F016S5 (16Mb) devices whose
device codes are A2H, A6H and AAH respectively.
Systems should be able to recognize all three codes.
The symmetrically blocked architecture and single 5V
operation provides a cost effective, high performance,
nonvolatile storage solution. The PC Card form factor
offers an industry standard pinout and mechanical
outline, allowing density upgrades without system
design changes.
The Value series is designed as a simple x16 linear
array of Flash devices. Two Flash devices in parallel
provide the lower and upper bytes for the 16 bit
access. The Value series does not provide access of
the ODD byte (D8 - D15) on the even byte data path
(D0 - D7).
WEDC’s standard Value Series Flash Card is shipped
with no attribute memory or CIS (Card Information
Structure) information. An option for 2KB of attribute
memory with CIS information is available. The CIS
for the WEDC Value series may also be stored in
Block 0 (even bytes, D0 - D7 only) of the Flash
memory, this option is available by request only.
WEDC’s standard cards are shipped with WEDC’s
Logo. Cards are also available with blank housings
(no Logo). The blank housings are available in both a
recessed (for label) and flat housing. Please contact
WEDC sales representative for further information on
Custom artwork.
