Product Summary

The AT26DF081A-SSU 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 AT26DF081A-SSU, 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. The AT26DF081A-SSU also offers a sophisticated method for protecting individual sectors against erroneous or malicious program and erase operations.
