AT5FC004

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 AT5FC004. This allows OEM manufacturers of portable system to eliminate the weight, power consumption and reliability issues associa-ted with electro-mechanical disk-based systems. The AT5FC 004 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 V) is required to perform any write operation, the AT5FC004 is suitable for the emerging "mobile" personal systems. The AT5FC 004 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 AT5FC004 contains a separate 2 Kbyte EEPROM memory for the card's attribute memory space.

The AT5FC004 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 AT5FC004, the software Driver and Formatter are also available. The Atmel Driver and Formatter utilizes a selfcontained spare sector replacement algorithm, enabled by Atmel's small 512-byte sectors, to achieve long term card reliability and endurance.
