AT25DF021A-MAHN-T Frequently Asked Questions (FAQs)

  • The AT25DF021A-MAHN-T has a minimum of 100,000 erase cycles per sector, and a total of 1,000,000 erase cycles for the entire device.
  • The AT25DF021A-MAHN-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 power-on reset timing is to hold the reset pin (RESET#) low for at least 10 ns after power-on, and then release it to allow the device to initialize properly.
  • Yes, the AT25DF021A-MAHN-T can be used in a multi-master SPI bus configuration, but it requires external logic to handle bus arbitration and collision detection.
  • The maximum clock frequency for the AT25DF021A-MAHN-T in SPI mode is 50 MHz.
