AT25SF081B-SSHD-B Frequently Asked Questions (FAQs)

  • The AT25SF081B-SSHD-B has a minimum of 100,000 erase cycles per sector, and a total of 1,000,000 erase cycles for the entire device.
  • The AT25SF081B-SSHD-B 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 clock frequency for the AT25SF081B-SSHD-B is up to 50 MHz. However, the device can operate at frequencies up to 100 MHz with some limitations.
  • Yes, the AT25SF081B-SSHD-B can be used in a multi-master SPI bus configuration. However, it is recommended to use a unique chip select signal for each device to avoid bus contention.
  • The AT25SF081B-SSHD-B has a built-in power-on reset circuit that ensures the device is in a known state after power-up. The device will automatically reset its internal state and release the chip select signal after power-on.
