AT25SF081B-SSHB-T Frequently Asked Questions (FAQs)

  • The AT25SF081B-SSHB-T has a minimum of 100,000 erase cycles, but the actual number of cycles may vary depending on the usage and operating conditions.
  • The hold pin (HOLD#) is an active low input that allows the device to be paused during a serial data transfer. When the hold pin is low, the device will ignore any serial data input and will not respond to any serial data output. You should connect the hold pin to VCC or use a pull-up resistor to ensure it is not accidentally triggered.
  • The recommended power-up sequence is to apply VCC first, followed by the input signals (SCK, SI, and CS#). This ensures that the device is properly initialized and ready for operation.
  • The optimal clock frequency depends on the specific application and system requirements. The AT25SF081B-SSHB-T supports clock frequencies up to 50 MHz, but you should consider factors such as system noise, signal integrity, and power consumption when selecting the clock frequency.
  • The WP# pin is an active low input that allows the device to be write-protected. When the WP# pin is low, the device will ignore any write commands and prevent accidental data modification. You can connect the WP# pin to VCC or use a pull-up resistor to enable write protection.
