Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.0V to 5.5V.
   • The device has low standby current (I_CC(STANDBY)) of 1.0 μA at 5.5V.

2. Data Retention:

   • The data retention time is 100 years under normal operating conditions.

3. Write Operations:

   • The write cycle time (t_WC) is 5.0 ms.
   • Each page write operation can handle up to 32 bytes.

4. Clock Frequency:

   • The maximum serial clock frequency (f_SCL) is 10.0 MHz.

5. Temperature Ranges:

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

6. Handling and Storage:

   • Store the device in a dry, cool place to ensure long-term reliability.
   • Avoid exposing the device to extreme temperatures or humidity.

7. Pin Configuration:

   • Refer to the datasheet for the specific pin configuration and connections.

8. Programming:

   • Use standard SPI (Serial Peripheral Interface) commands for read, write, and other operations.
   • Ensure the correct sequence of commands to avoid data corruption.

9. Protective Measures:

   • Use appropriate decoupling capacitors near the power supply pins to filter out noise.
   • Implement ESD (Electrostatic Discharge) protection measures to prevent damage during handling.

10. Testing:

    • Before integrating the device into a system, perform initial testing to verify functionality and performance.
