AT25DF321A-SH-B

The <bold>AT25DF321A</bold> 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 AT25DF321A, 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.

• Flexible, optimized erase architecture for code + data storage applications
• Individual sector protection with Global Protect/Unprotect feature
• Sector Lockdown
• 128byte, One-Time Programmable (OTP) Security Register
• Flexible Programming
• Fast Program and Erase Times
• Automatic checking and reporting of erase/program failures
• Software controlled reset
