Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 2.7V to 5.5V.
   • Connect the Vcc pin to the positive power supply and GND to the ground.

2. Temperature Range:

   • The device operates reliably between -40°C and 85°C.

3. Current Consumption:

   • In standby mode, the current consumption is typically 0.1 μA.
   • In active mode, the current consumption is typically 3.5 mA.

4. Access and Cycle Times:

   • The access time (tacc) is typically 45 ns.
   • The cycle time (tcycle) is typically 60 ns.

5. Data Retention:

   • Data retention is guaranteed for up to 10 years.

6. Write Operations:

   • Writing a byte takes approximately 5 μs.
   • Writing a page takes approximately 2 ms.

7. Erase Operations:

   • Erasing a sector takes approximately 10 ms.
   • Erasing the entire chip takes approximately 50 ms.

8. Endurance:

   • The device can withstand up to 100,000 write/erase cycles.

9. Data Integrity:

   • Each sector has 256 bits dedicated to data integrity checks.

10. Handling:

    • Handle the device with care to avoid static damage.
    • Follow standard ESD (Electrostatic Discharge) precautions.

11. Storage:

    • Store the device in a dry, cool place when not in use.

12. Testing:

    • Perform initial testing under controlled conditions to ensure proper functionality.

13. Documentation:

    • Refer to the datasheet for detailed timing diagrams and application notes.
