PCMCIA Flash Memory Card
FLD Series
March 2003 Rev. 6
ECO #16058
PCMCIA Flash Memory Card - 4 MEGABYTE through
40 MEGABYTE (AMD based)
GENERAL DESCRIPTION
WEDCs PCMCIA Flash memory cards offer high den-
sity 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 con-
tains a connector, an array of Flash memories pack-
aged in TSOP packages and card control logic. The
card control logic provides the system interface and
controls the internal Flash memories. Combined with
file management software, such as Flash Translation
Layer (FTL), WEDC Flash cards provide removable high-
performance disk emulation.
The WEDC FLD series is based on AMD Flash
memo-
ries. The FLD series offers byte wide and word wide
operation, low power modes and Card Information Struc-
ture (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.

ARCHITECTURE OVERVIEW
WEDCs FLD series is designed to support from two to
twenty (see Block diagram) 16Mb components, provid-
ing a wide range of density options. Cards are based
on the Am29F017 (16Mb) device for 5V only applica-
tions. The device code for the Am29F017 is 3Dh and the
manufacturers ID is 01h. This card is compatible with
D series cards from AMD. Cards utilizing 16Mb compo-
nents provide densities ranging from 4MB to 40MB in
4MB 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 (128kB)blocks. Write,
read 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 FLD series cards conform with the PC Card
Standard (formerly PCMCIA) and supported JEIDA, pro-
viding electrical and physical compatibility. The PC Card
form factor offers an industry standard pinout and me-
chanical outline, allowing density upgrades without sys-
tem design changes.
WEDCs standard cards are shipped with WEDCs
silkscreen design. Cards are also available with blank
housings (no silkscreen). The blank housings are avail-
able in both a recessed (for label) and flat housing.
Please contact your WEDC sales representative for fur-
ther information on Custom artwork.

(2) Stress greater than those listed under Absolute Maximum ratings may cause permanent damage to the device.
This is a stress rating only and functional operation at these or any other conditions greater than those indicated in
the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
