ARCHITECTURE OVERVIEW
WEDC’s FLE series is designed to support up to twenty (see
Block diagram) 32Mb components, providing a wide range
of density options. Cards are based on the Am29F032
(32Mb) device for 5V only applications. The device code
for the Am29F032 is 41h and the manufacturer’s ID is 01h.
Systems should be able to recognize these codes. Cards
utilizing 32Mb components provide densities ranging from
8MB to 64MB in 8MB increments.
In support of the PC Card (PCMCIA) standard for word
wide access, devices are paired. Therefore, the Flash
array is structured in 64K word blocks. Write, read and
block erase operations can be performed as either a
word or byte wide operation . By multiplexing A0, CE1#
and CE2#, 8-bit hosts can access all data on data lines
DQ0 - DQ7. The FLE series cards conform with the PC
Card Standard (formerly PCMCIA) and supported 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
silkscreen design. Cards are also available with blank
housings (no silkscreen). The blank housings are available
in both a recessed (for label) and
fl
at housing. Please
contact your WEDC sales representative for further
information on Custom artwork.
GENERAL DESCRIPTION
WEDC’s PCMCIA Flash memory cards offer the highest
density, linear Flash solid state storage solutions for code
and data storage, high performance disk emulation and
execute in place (XIP) applications in mobile PC and
dedicated (embedded) equipment.
Packaged in a PCMCIA type I housing, each card contains
a connector, an array of Flash memories packaged in
TSOP packages and card control logic. The card control
logic provides the system interface and controls the
internal Flash memories. Combined with
fi
le management
software, such as Flash Translation Layer (FTL), WEDC
Flash cards provide removable high-performance disk
emulation.
The WEDC FLE series is based on AMD Flash memories.
The FLE series offers byte wide and word wide operation,
low power modes and Card Information Structure (CIS)
for easy identification of card characteristics.
Note: Standard options include attribute memory. Cards without attribute memory are
available. Cards are also available with or without a hardware write protect switch.
