WEDC’s FLC Series Flash memory cards offer medium/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.
FLC series cards conform to PCMCIA international standard.
The card’s control logic provides the system interface and
controls
the
internal
Flash
memories.
Card
can
be
read/written in byte-wide or word-wide mode which allows
for flexible integration into various systems. Combined with
file management software, such as Flash Translation Layer
(FTL), FLC Flash cards provide removable high-performance
disk emulation.
The FLC series cards contain separate 2kB EEPROM
memory for Card Information Structure (CIS) which can be
used for easy identification of card characteristics.
The WEDC FLC series is based on AMD Am29F040 Flash
memories; the FLC04 is a direct equivalent of AMD’s
AmC0XXCFLKA, however it offers wider range of
intermediate memory capacities.
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
FLC Series Cards are based on the Am29F040 (4Mb) components which work with single 5V applications.
Manufacture/Device code is 01h/A4h.
FLC series is designed to support from 2 to 20components, providing densities ranging from 1MB to 10MB in 1MB
increments. In support of the PC Card 95 standard for word wide access devices are paired. Write, read and 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 FLC series cards conform to the PC Card Standard
(PCMCIA) and 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 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.

2) Shows density for which specified address bit is MSB. Higher order address bits are N.C. (i.e. 4MB A21 is MSB A22 - A25 are NC).
3) For the 3MB card the memory will wrap at the 4MB boundary, for 5MB, 6MB, and & 7MB cards the memory will wrap at the 8MB
boundary, for 9MB and 10MB cards the memory will wrap at the 16MB boundary.

Name and Function
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.
The memory will wrap at the card density boundary (see PINOUT, note 3).
The system should not try to access memory beyond the card density. A25
is the most significant bit. A24 – A25 are not connected.
DATA INPUT/OUTPUT:
DQ0 THROUGH DQ15 constitute the bi-directional
databus. DQ0 – DQ7 constitute the lower (even) byte and DQ8 – DQ15 the
upper (odd) byte. DQ15 is the MSB.
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.
OUTPUT ENABLE:
Active low signal gating read data from the memory
card.
WRITE ENABLE:
Active low signal gating write data to the memory card.
READY/BUSY OUTPUT:
Indicates status of internally timed erase or
program algorithms. This signal is not connected.
CARD DETECT 1 and 2:
Provide card insertion detection. These signals
are internally connected to ground on the card. The host shall monitor these
signals to detect card insertion (pulled-up on host side).
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".
PROGRAM/ERASE POWER SUPPLY:
Provides programming voltages
12.0V for lower byte (D0 – D7) memory components. This signal is not
connected.
PROGRAM/ERASE POWER SUPPLY:
Provides programming voltages
12.0V for upper byte (D8 – D15) memory components. This signal is not
connected.
CARD POWER SUPPLY:
(5.0V).
CARD GROUND
ATTRIBUTE MEMORY SELECT :
Active low signal, enables access to
Attribute Memory Plane, occupied by Card Information Structure and Card
Registers.
RESET:
Active high signal for placing cards in Power-on default state. This
signal is not connected.
WAIT:
This signal is pulled high internally for compatibility. No wait states
are generated.
BATTERY VOLTAGE DETECT:
These signals are pulled high to maintain
SRAM card compatibility.
VOLTAGE SENSE:
Notifies the host socket of the card's VCC
requirements. VS1 and VS2 are open to indicate a 5V card.
RESERVED FOR FUTURE USE
