AT25FF321A-UUN-T Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the AT25FF321A-UUN-T is 1.7V to 3.6V.
  • When the device is busy, it will ignore any incoming write operations. It is recommended to poll the WIP (Write In Progress) bit in the status register to check if the device is busy before initiating a page write operation.
  • The WP pin is used to enable or disable write protection for the entire device or a specific sector. When the WP pin is low, the device or sector is write-protected, and when it is high, write operations are allowed.
  • To perform a sector erase operation, send the Sector Erase command (0x20) followed by the sector address. The device will then erase the entire sector.
  • The AT25FF321A-UUN-T has a minimum of 100,000 erase cycles per sector, and a maximum of 1,000,000 erase cycles per device.
