AT25SL321-SSHE-T Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the AT25SL321-SSHE-T is 2.7V to 3.6V, as specified in the datasheet. However, it's essential to note that the device can operate down to 2.5V, but with reduced performance and reliability.
  • To ensure reliable data retention, it's crucial to follow the recommended storage conditions, such as storing the device in a cool, dry place, away from direct sunlight and radiation. Additionally, the device should be powered down before storage, and the storage temperature should be within the specified range of -40°C to 85°C.
  • The AT25SL321-SSHE-T supports up to 100,000 erase cycles, as specified in the datasheet. However, it's essential to note that the actual number of erase cycles may vary depending on the usage and operating conditions.
  • During power-up and power-down sequences, the HOLD pin should be pulled high to ensure that the device is not in the hold state. This is because the HOLD pin is internally pulled low during power-up and power-down, and pulling it high ensures that the device is not held in a state that could cause data corruption or other issues.
  • The recommended clock frequency for the AT25SL321-SSHE-T is up to 50 MHz, as specified in the datasheet. However, it's essential to note that the actual clock frequency may vary depending on the system design and operating conditions.
