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
PC
and
embedded
applications.
The WEDC FVB Value series is based on AMD
Flash memories. Current cards are based on the
AMD 29F016 (2MB) device whose manufacturer
and device code is 01 and ADH respectively. 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
Logo. Cards are also available in 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
