FLV Series
White Electronic Designs
PCMCIA Flash Memory Card
2 MEGABYTE through 40 MEGEBYTE (Intel/Sharp based)
The WEDC FLV series is based on Intel/Sharp Flash
memories.
FEATURES
Low cost High Density Linear Flash Card
Supports 3V or 5V only systems
x8/ x16 Data Interface
Note: Standard options include attribute memory. Cards without attribute memory are
available. Cards are also available with or without a hardware write protect switch.
Based on Intel/Sharp FlashFile Components
ARCHITECTURE OVERVIEW
Fast Read Performance
150ns @ 5V
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.
200ns @ 3.3V
High Performance Random Writes
8µs Typical Word Write Time @ 5V
17µs Typical Word Write Time @ 3.3V
Automated Write and Erase Algorithms
Command User Interface
100,000 Erase Cycles per Block
64K word symmetrical Block Architecture
PC Card Standard Type I Form Factor
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 multiplexingA0, CE1# and CE2#,
8-bit hosts can access all data on data lines DQ0 - DQ7.
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.
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.
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 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.
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.
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.
