AT25256B-SSHL-B Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the AT25256B-SSHL-B is 1 MHz.
  • Page writes to the AT25256B-SSHL-B should be done in blocks of 64 bytes, and the device will automatically increment the address pointer after each byte is written.
  • The WP (Write Protect) pin is used to prevent writes to the entire memory array. When WP is low, the entire array is write-protected.
  • A chip erase can be performed by sending the Chip Erase command (0x99) to the device, followed by the Chip Erase confirmation code (0x00).
  • The AT25256B-SSHL-B has an endurance of 100,000 cycles per byte.
