Instructions for AT25640N-10SI-2.7

1. Power Supply:

   • Ensure the operating voltage (Vcc) is within the range of 1.7V to 3.6V.
   • The device has low standby current (1 μA) and active current (3 mA).

2. Programming:

   • The write cycle time (tWC) is between 2 ms and 5 ms.
   • The page program time (tPP) is also between 2 ms and 5 ms.

3. Erase Operations:

   • Sector erase time (tSE) ranges from 35 ms to 100 ms.
   • Chip erase time (tCE) ranges from 180 ms to 300 ms.

4. Data Retention:

   • The device retains data for a minimum of 20 years and up to 100 years.

5. Write Protection:

   • The write protect pin (WP) can be used to prevent accidental writes. Set it high to enable write protection.

6. Hold Function:

   • The hold pin (HOLD) can be used to pause ongoing operations. Set it high to activate the hold function.

7. Temperature Considerations:

   • The operating temperature range is from -40°C to 85°C.
   • The storage temperature range is from -65°C to 150°C.

8. Pin Configuration:

   • Refer to the datasheet for detailed pin configuration and functions.

9. Communication Protocol:

   • The device supports standard SPI communication protocol. Ensure the correct SPI settings are configured for proper operation.

10. Handling and Storage:

    • Handle the device with care to avoid electrostatic discharge (ESD) damage.
    • Store the device in a dry and cool environment to ensure long-term reliability.
