AT25SF041B-SHD-B Frequently Asked Questions (FAQs)

  • The AT25SF041B-SHD-B 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#) should be pulled high during power-up and power-down to prevent any unwanted writes or erases. It's recommended to connect a pull-up resistor to the HOLD# pin to ensure it remains high during these transitions.
  • The recommended clock frequency for the SPI interface is up to 50 MHz, but it can operate at lower frequencies as well. However, the maximum clock frequency may vary depending on the system design and layout.
  • The WP# pin is used to protect the entire memory array from writes and erases. When WP# is low, the entire memory array is write-protected. When WP# is high, the memory array is not protected, and writes and erases are allowed. It's recommended to connect a pull-up resistor to the WP# pin to ensure it remains high during normal operation.
  • The Deep Power-Down (DPD) mode is a low-power state that reduces the power consumption of the device to a minimum. In this mode, the device is not accessible, and all internal operations are stopped. The DPD mode is useful for battery-powered devices or systems that require low power consumption during idle periods.
