AT25DF321A-SH-T Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the AT25DF321A-SH-T is 2.7V to 3.6V.
  • The AT25DF321A-SH-T uses a page write cycle of 256 bytes. To handle page write cycles, you need to send a write enable command, followed by the page address and the data to be written. The device will automatically handle the page write cycle internally.
  • The WP (Write Protect) pin is used to prevent accidental writes to the device. When the WP pin is tied low, the entire memory array is protected from writes. When the WP pin is tied high, the device operates normally.
  • To perform a sector erase on the AT25DF321A-SH-T, you need to send a sector erase command, followed by the sector address. The device will automatically erase the entire sector.
  • The AT25DF321A-SH-T has a maximum of 100,000 erase cycles per sector.
