PCMCIA Flash Memory Card
FLA Series
PCMCIA Flash Memory Card
General Description
1 MEGABYTE through 40 MEGABYTE (Intel/Sharp based)
Features
WEDC’s FLA 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.
• Low cost High Density Linear Flash Card
• Supports 5V only systems or 5V systems with
12V VPP
• Based on Intel/Sharp FlashFile Components
FLA series cards conform to PCMCIA international standard.
• Fast Read Performance
- 150ns or 200ns Maximum Access Time
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), FLA Flash cards provide removable high-performance
disk emulation.
• x8 / x16 Data Interface
• High Performance Random Writes
- 8µs Typical Word Write Time
• Automated Write and Erase Algorithms
- Command User Interface
The FLA series offers low power modes controlled by
registers. Standard cards contain separate 2kB EEPROM
memory for Card Information Structure (CIS) which can be
used for easy identification of card characteristics.
• 100,000 Erase Cycles per Block
• 64K word symmetrical Block Architecture
• PC Card Standard Type I Form Factor
The WEDC FLA 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
WEDC’s FLA series is designed to support from 2 to 20, 4Mb, 8Mb or 16Mb components, providing a wide range
of density options. Cards are based on the 28F008SA (8Mb) for 12V VPP applications or on the 28F004S5 (4Mb),
28F008S5 (8Mb) and 28F016S5 (16Mb) devices for 5V only applications. Devices codes for the 28F004S5,
28F008SA, 28F008S5 and the 28F016S5 are: A7H, A2H, A6H and AAh respectively. Systems should be able to
recognize all four 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. 4
Mbit memory devices are used only for smallest capacity cards (1MB).
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-FLA36 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 FLA51 - FLA66 do not have registers).
The FLA series cards conform with 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.
