Description

The AT25DF041A-SH-T is one member of the AT25DF041A series.The AT25DF041A is a serial interface Flash memory device designed for use in a wide variety of high-volume consumer-based applications in which program code is shadowed from Flash memory into embedded or external RAM for execution. The flexible erase architecture of the AT25DF041A, with its erase granularity as small as 4 Kbytes, makes it ideal for data storage as well, eliminating the need for additional data storage EEPROM devices.

Features of the AT25DF041A-SH-T are:(1)single 2.3V - 3.6V or 2.7V - 3.6V supply; (2)serial peripheral interface (spi) compatible-supports SPI modes 0 and 3; (3)70 MHz maximum clock frequency; (4)automatic checking and reporting of erase/program failures; (5)JEDEC Standard manufacturer and device ID read methodology; (6)endurance: 100,000 program/erase cycles; (7)data retention: 20 years; (8)complies with full industrial temperature range.The physical sectoring and the erase block sizes of the AT25DF041A have been optimized to meet the needs of today's code and data storage applications. By optimizing the size of the physical sectors and erase blocks, the memory space can be used much more efficiently.

The absolute maximum ratings of the AT25DF041A-SH-T can be summarized as:(1)storage temperature:-65 to 150;(2)all input voltages(including NC pins) with respect to ground:-0.6 to 4.1 V;(3)all output voltages with respect to ground:-0.6 to Vcc+0.5V;(4)temperature under bias:-55 to +125.The AT25DF041A also offers a sophisticated method for protecting individual sectors against erroneous or malicious program and erase operations. By providing the ability to individually protect and unprotect sectors, a system can unprotect a specific sector to modify its contents while keeping the remaining sectors of the memory array securely protected. This is useful in applications where program code is patched or updated on a subroutine or module basis, or in applications where data storage segments need to be modified without running the risk of errant modifications to the program code segments. In addition to individual sector protection capabilities,the AT25DF041A incorporates Global Protect and Global Unprotect features that allow the entire memory array to be either protected or unprotected all at once.
