AT45DB321E-SHF-B Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the AT45DB321E-SHF-B is 2.7V to 3.6V.
  • The HOLD pin should be pulled high during power-up and power-down sequences to prevent unwanted data corruption.
  • The maximum clock frequency supported by the AT45DB321E-SHF-B is 66 MHz.
  • A reliable POR circuit can be implemented using a voltage supervisor IC or a simple RC circuit with a capacitor and a resistor to ensure a clean power-on reset.
  • The recommended method for erasing the entire memory array is to use the Chip Erase command (0xC7) followed by a confirmation of the erase operation using the Read Status Register command (0xD7).
