AT25XE321D-SSHN-T Frequently Asked Questions (FAQs)

  • The AT25XE321D-SSHN-T has a maximum of 100,000 erase cycles per sector, and a total of 2,000,000 erase cycles for the entire device.
  • The AT25XE321D-SSHN-T has a 256-byte page write buffer. If the buffer overflows, the device will automatically wrap around to the beginning of the page and continue writing data.
  • The recommended method is to poll the Write-In-Progress (WIP) bit in the Status Register (SR) until it is cleared, indicating that the write operation is complete.
  • Yes, the AT25XE321D-SSHN-T supports multi-master operation, but it requires external logic to handle arbitration and collision detection.
  • The minimum clock frequency required is 100 kHz, but it is recommended to use a clock frequency of at least 1 MHz for optimal performance.
