Data files and applications programs can be stored on the AT5FC512. This allows OEM manufacturers of portable system to eliminate the weight, power consumption and reliability issues associated with electro-mechanical disk-based systems. The AT5FC512 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 AT5FC512 is suitable for the emerging "mobile" personal systems. The AT5FC512 is compatible with 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 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 lowlevel organization of data on the PC card. The AT5FC512 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 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 Atmel’s small 256-byte sectors, to achieve long term card reliability and endurance.

This 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 -0.5V. During voltage transients, inputs may overshoot VSS to -2.0V for periods of up to 20 ns. Maximum DC voltage on output and I/O pins is VCC + 0.5V. During voltage transitions, outputs may overshoot to VCC + 2.0V for periods up to 20 ns. 2. No more than one output shorted at a time. Duration of the short circuit should not be greater than one second. Conditions equal VOUT = 0.5V or 5.0V, VCC = Max.
