AT25DF321A-MH-Y Frequently Asked Questions (FAQs)

  • The AT25DF321A-MH-Y has a maximum of 100,000 erase cycles per sector, and 1,000,000 program/erase cycles per device.
  • The AT25DF321A-MH-Y uses a page write buffer to handle page write operations. The buffer is 256 bytes, and the device can perform a page write operation in 1.4 ms (typical).
  • The WP# (Write Protect) pin is used to prevent write operations to the status register and the memory array. When the WP# pin is low, the device is in write-protect mode, and when it is high, the device is in normal operation mode.
  • The AT25DF321A-MH-Y has a built-in power-on reset circuit that resets the device to its default state when the power supply voltage (VCC) rises above the minimum operating voltage (VCC(min)).
  • The recommended operating voltage range for the AT25DF321A-MH-Y is 2.7V to 3.6V.
