AT25M02-SSHD-B Frequently Asked Questions (FAQs)

  • The AT25M02-SSHD-B has a minimum of 100,000 write cycles, but the actual number of write cycles may vary depending on the usage and operating conditions.
  • To handle page write buffer underrun errors, ensure that the page write buffer is fully loaded before initiating a write operation. Also, implement error detection and correction mechanisms in your firmware to handle such errors.
  • The recommended power-up sequence is to apply VCC before applying the clock signal. During power-down, remove the clock signal before removing VCC. This ensures that the device is properly initialized and avoids any potential issues.
  • To implement secure erase, use the Chip Erase command (0xC7) to erase the entire device. This will set all memory locations to their default state. Note that this operation is irreversible, so ensure that you have backed up any critical data before performing a secure erase.
  • The maximum clock frequency for the AT25M02-SSHD-B is 20 MHz. Operating the device above this frequency may result in unreliable operation or damage to the device.
