PC Card Standard Type I Form Factor
WEDC's PCMCIA Flash memory cards offer high
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 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 file management software, such as Flash
Translation Layer (FTL), WEDC Flash cards provide
removable high-performance disk emulation.
The WEDC FLA series is based on AMD Flash
memories. The FLB 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.
PCMCIA Flash Memory Card 2 MEGABYTE through 40 MEGABYTE (AMD based)
WEDC's FLB series is designed to support from two to twenty (see Block diagram) 8Mb or 16MB components,
providing a wide range of density options. Cards are based on the Am29F080 (8Mb) or Am29F016 (16Mb) devices
for 5V only applications. Devices codes for the Am29F080 and Am29F016 are D5H and ADH respectively.
Systems should be able to recognize both codes. Cards utilizing the 8Mb components provide densities ranging
from 2MB to 20MB in 2MB increments, cards utilizing 16Mb components provide densities ranging from 4MB to
40MB in 4MB increments.
In support of the PC Card 95 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
FLB 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 flat housing. Please contact
WEDC sales representative for further information on Custom artwork.

Symbol
Type
Name and Function
A0 - A25
INPUT
ADDRESS INPUTS: A0 through A25 enable direct addressing of
up to 64MB of memory on the card. Signal A0 is not used in word
access mode. A25 is the most significant bit
DQ0 - DQ15
INPUT/OUTPUT
DATA INPUT/OUTPUT: DQ0 THROUGH DQ15 constitute the
bi-directional databus. DQ15 is the MSB.
CE1#, CE2#
INPUT
CARD ENABLE 1 AND 2: CE1# enables even byte accesses, CE2#
enables odd byte accesses. Multiplexing A0, CE1# and CE2# allows
8-bit hosts to access all data on DQ0 - DQ7.
OE#
INPUT
OUTPUT ENABLE: Active low signal gating read data from the
memory card.
WE#
INPUT
WRITE ENABLE: Active low signal gating write data to the
memory card.
RDY/BSY#
OUTPUT
READY/BUSY OUTPUT: Indicates status of internally timed erase
or program algorithms. A high output indicates that the card is ready
to accept accesses. A low output indicates that one or more devices
in the memory card are busy with internally timed erase or write
activities.
CD1#, CD2#
OUTPUT
CARD DETECT 1 and 2: Provide card insertion detection. These
signals are connected to ground internally on the memory card. The
host socket interface circuitry shall supply 10K-ohm or larger pull-up
resistors on these signal pins.
WP
OUTPUT
WRITE PROTECT: Write protect reflects the status of the Write
Protect switch on the memory card. WP set to high = write protected,
providing internal hardware write lockout to the Flash array.
If card does not include optional write protect switch, this signal will
be pulled low internally indicating write protect = "off".
VPP1, VPP2
N.C.
PROGRAM/ERASE POWER SUPPLY: Not connected for 5V
only card.
VCC
CARD POWER SUPPLY: 5.0V for all internal circuitry.
GND
GROUND: for all internal circuitry.
REG#
INPUT
ATTRIBUTE MEMORY SELECT : provides access to Flash
memory card registers and Card Information Structure in the
Attribute Memory Plane.
RST
INPUT
RESET: Active high signal for placing card in Power-on default
state. Reset can be used as a Power-Down signal for the memory
array.
WAIT#
OUTPUT
WAIT: This signal is pulled high internally for compatibility. No
wait states are generated.
BVD1, BVD2
OUTPUT
BATTERY VOLTAGE DETECT: These signals are pulled high to
maintain SRAM card compatibility.
VS1, VS2
OUTPUT
VOLTAGE SENSE: Notifies the host socket of the card's VCC
requirements. VS1 and VS2 are open to indicate a 5V card has been
inserted.

4MB for 16Mb components) This represents a single pair of devices. For higher densities multiply the number of device
pairs by the specified current in the table. For example a 40MB card will use 10 device pairs of 16Mb components.
The maximum ICCD will be 10 x 40A = 400A. The maximum ICCS will be 10 x 230A = 2.3mA.
