GENERAL DESCRIPTION
WEDCs 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 cards 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.
The WEDC FLV series is based on Intel/Sharp Flash
memories.
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 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 A0, CE1
and CE2, 8-bit hosts can access all data on data lines
DQ0 - DQ7.
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.
WEDCs standard cards are shipped with WEDCs 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.
