PCMCIA Flash Memory Card

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.
