Description

Atmel’s Flash Memory Card provides the highest system level
performance for data and file storage solutions to the portable
PC market segme nt. Data files and applic ations program s can be
stored on the AT5FC001. This allows OEM manufacturers of
portable system to eliminate the weight, powe r consumption and
reliability issues associated with electro-mechanical disk-based
systems. The AT5F C001 requires a single voltage power sup ply
for total system operation. No batteries are needed for data re­tention due to its Flash-based technology. Since no high volta ge
(12-volt) is required to perform any write operation, the
AT5FC001 is suitable for the emerging "mobile" personal sys­tems.

The AT5FC001 is co mp atible with the 68- pin PC M CIA/ JEI DA
international standard. Atmel’s Flash Memory Cards can be
read in either a byte-wide or word-wide mode which allows for
flexible integration into various system platforms. It can be read
like any typical PCMCIA SRAM or ROM card.

Block Diagram

The Card Information Structure (CIS) can be written by the
OEM or by Atmel at the attribute memory address space using a
format utility. The CIS appears at the beginning of the card’s
attribute memory space and defines the low-level organization
of data on the PC card. The AT5FC001 contains a separate
2 Kbyte EEPROM memory for the card’s attribute memory
space.

The third party software solutions such as AWARD Software’s
CardWare system and the SCM’s Flash File System (FFS),
enables Atmel’s Flash Memory Card to emulate the function of

essentially all the major brand personal computers that are
DOS/Windows compatible.

For some unique portable computers, such as the
HP200/100/95LX series, the so ftw ar e Dr iver an d Fo rmatter are
also available. The Atmel Driver and Formatter utilizes a self­contained spare sector replacement algorithm, enabled by At­mel’s small 256-byte sectors, to achieve long term card
reliability and endurance.

*NOTICE: Stresses beyond those listed under "Absolute Maximum

Ratings" may cause perm an en t dam ag e to the card . T his is a stress
rating only and functional operation of the card at these or any
other conditions beyond those indicated in the
operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended pe­riods may affect device reliability.

Notes:

1. Minimum DC voltage on input or I/O pins is -0.5 V. During volt­age transients, inputs may overshoot V
up to 20 ns. Maximum DC voltage on output and I/O pins is
