Description

Atmel’s Flash Memory Card provides the highest system level

performance for data and file storage solutions to the portable

PC market segment. Data files and applications programs can be

stored on the AT5FC002. This allows OEM manufacturers of

portable system to eliminate the weight, power consumption and

reliability issues associated with electro-mechanical disk-based

systems. The AT5FC002 requires a single voltage power supply

for total system operation. No batteries are needed for data re-

tention due to its Flash-based technology. Since no high voltage

(12-volt) is required to perform any write operation, the

AT5FC002 is suitable for the emerging "mobile" personal sys-

tems.

The AT5FC002 is compatible with the 68-pin PCMCIA/JEIDA

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.

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 AT5FC002 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 software Driver and Formatter are

also available. The Atmel Driver and Formatter utilizes a self-

contained spare sector replacement algorithm, enabled by At-

mel’s small 512-byte sectors, to achieve long term card

reliability and endurance.
