PCMCIA Flash Memory Card

FLE Series

August 2000 Rev. 4 - ECO #13129

PCMCIA Flash Memory Card

General Description

Architecture Overview

WEDC’s PCMCIA Flash memory cards offer the

highest 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.

Packaged in a PCMCIA type I housing, each card

contains a connector, an array of Flash memories

packaged in TSOP packages and card control logic.

The card control logic provides the system interface

and controls the internal Flash memories. Combined

with file management software, such as Flash

Translation Layer (FTL), WEDC Flash cards provide

removable high-performance disk emulation.

The WEDC FLE series is based on AMD Flash

memories. The FLE series offers byte wide and word

wide operation, low power modes and Card

Information Structure (CIS) for easy identification of

card characteristics.

Note: Standard options include attribute memory.

Cards without attribute memory are available. Cards

are also available with or without a hardware write

protect switch.

WEDC’s FLE series is designed to support up to twenty (see Block diagram) 32Mb components, providing a wide

range of density options. Cards are based on the Am29F032 (32Mb) device for 5V only applications. The device

code for the Am29F032 is 41h and the manufacturer’s ID is 01h. Systems should be able to recognize these codes.

Cards utilizing 32Mb components provide densities ranging from 8MB to 64MB in 8MB increments.

In support of the PC Card (PCMCIA) standard for word wide access, devices are paired. Therefore, the Flash array

is structured in 64K word 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

FLE series cards conform with the PC Card Standard (formerly PCMCIA) and supported 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 silkscreen design. Cards are also available with blank housings

(no silkscreen). 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.
