ARCHITECTURE OVERVIEW
WEDC’s FLV series is designed to support from 2 to 20
of 8Mb or 16MB components, providing a wide range
of density options. Cards are based on the 28F008SC
(8Mb) and 28F016SC (16Mb) devices for 3.3V or 5V
only applications. Devices codes for the 28F008SC and
the 28F016SC are: A6H and AAH respectively. Systems
should be able to recognize all the 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 (128kBytes) blocks. Write, read and
block erase operations can be performed as either a word
or byte wide operation . By multiplexing A
0
, CE
1#
and CE
2#
,
8-bit hosts can access all data on data lines DQ
0
- DQ
7
.
The
FLA21-FLA28
series also supports the following
PCMCIA compatible register functions: Soft Reset via the
Configuration Option Register, Power Down (sleep mode)
via the Configuration and Status Register and monitoring
of Ready/Busy, Soft Reset and Power Down via the Card
Status Register (cards without attribute memory and
versions
FLV51-FLV58
do not have registers).
FLV51-
FLV58
do not support Ready/Busy and Reset signals.
The FLV series cards conform to the PC Card (PCMCIA)
and JEIDA standards, 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 your WEDC sales
representative for further information on Custom artwork.
GENERAL DESCRIPTION
WEDC’s FLV Series 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.
FLV series cards conform to the PCMCIA international
standard
The card’s control logic provides the system interface and
controls the internal Flash memories. The 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), FLV Flash cards provide removable high-
performance disk emulation.
The FLV series offers low power modes controlled by
registers. Cards contain separate 2kB EEPROM memory
for Card Information Structure (CIS) which can be used for
easy identification of card characteristics.

CARD SIGNAL DESCRIPTION
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
DATA INPUT/OUTPUT:
DQ0 THROUGH DQ15 constitute the bi-directional databus. 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. 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.
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 for card. Not connected for 3.3V/5V only card.
CARD POWER SUPPLY:
5.0V for all internal circuitry

Active high signal for placing card in Power-on default state. Reset can be used as a Power-Down control for
the memory array.
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.
