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 AT5FC256. This allows OEM manufacturers of portable system to eliminate the weight, power consumption and reliability issues asso-ciated with electro-mechanical disk-based systems. The AT5FC 256 requires a single voltage power supply for total system operation. No batteries are needed for data retention due to its Flash-based technology. Since no high voltage (12-volt) is required to perform any write operation, the AT5FC256 is suitable for the emerging "mobile" personal systems.

The AT5FC256 i s compat ible wi th the 68-pin PCMCIA/JEIDA international standard. Atmel's Flash Memory Cards can be read in either a byte-wide or wordwide mode which allows for flexible integration into various system plat-forms. 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 lowlevel organization of data on the PC card. The AT5FC256 contains a separate 2K byte 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 AT5FC256, the software Driver and Formatter are also available. The Atmel Driver and Formatter utilizes a self-contained spare sector replacement algorithm, enabled by Atmel's small 256-byte sectors, to achieve long term card reliability and endurance.
