SST25WF040B-40I/SN Frequently Asked Questions (FAQs)

  • The SST25WF040B-40I/SN 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 use an external pull-up resistor to ensure the pin is held high during these transitions.
  • The recommended clock frequency for the SST25WF040B-40I/SN is up to 104 MHz. However, the actual clock frequency may vary depending on the system design and operating conditions.
  • The WP# pin should be tied to VCC or left floating during normal operation to allow writes to the device. Tying the WP# pin to GND will prevent writes to the device.
  • The Deep Power-Down (DPD) mode is a low-power state that reduces the device's power consumption to a minimum. It's useful for battery-powered devices or systems that require low power consumption during idle periods.
