AT25SF081B-SHB-T Frequently Asked Questions (FAQs)

  • The maximum number of erase cycles for the AT25SF081B-SHB-T is 100,000 cycles.
  • To handle page write buffer overflow, you should check the WEL (Write Enable Latch) bit in the status register after each page write operation. If the WEL bit is cleared, it indicates that the page write buffer is full, and you should wait until the buffer is empty before performing the next write operation.
  • The recommended power-on reset procedure for the AT25SF081B-SHB-T is to apply a power-on reset pulse of at least 10ms duration to ensure that the device is properly initialized.
  • You can determine the device density and organization by reading the JEDEC ID (0x1F 0x45 0x01) and the Device ID (0x13 0x45 0x01) registers.
  • 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 any write operations will be ignored.
