Instructions for FM24CL04B-G

1. Power Supply Connection:

   • Connect the Vcc pin to a power supply within the range of 1.8V to 5.5V.
   • Ensure the GND pin is connected to the ground.

2. Initialization:

   • Before performing any read or write operations, ensure the device has been powered up and stabilized.

3. Reading Data:

   • Use standard I2C protocol commands to initiate read operations.
   • Address the FM24CL04B-G using its I2C address.

4. Writing Data:

   • Initiate write operations by sending the appropriate I2C start condition followed by the device address and memory address.
   • Data can be written in pages (up to 32 bytes at a time).

5. Write Cycle Time:

   • Allow a minimum of 5ms between successive write cycles to ensure data integrity.

6. Environmental Considerations:

   • Operate the device within the temperature range of -40°C to +85°C for optimal performance.
   • Store the device in environments ranging from -65°C to +125°C.

7. Data Retention:

   • Data retention is guaranteed for up to 10 years at temperatures up to 45°C.

8. Standby Mode:

   • To minimize power consumption, put the device into standby mode when not in use. The current draw in this mode is minimal (0.1μA to 1μA at 5.5V).

9. Handling Precautions:

   • Follow ESD handling precautions to prevent damage to the component.
   • Avoid exposing the device to excessive humidity or corrosive environments.
