Instructions for Use:

1. Power Supply Connection:

   • Connect VCC to the positive supply voltage within the specified range (1.7V to 5.5V).
   • Connect GND to the system ground.

2. I2C Interface Configuration:

   • Ensure SDA (Serial Data Line) and SCL (Serial Clock Line) are connected to the microcontroller or processor.
   • Use pull-up resistors on both SDA and SCL lines, typically between 1.8k惟 and 10k惟 depending on bus length and speed.

3. Address Configuration:

   • The device has a fixed I2C address which can be found in the datasheet. No address pins are available for configuration.

4. Writing Data:

   • Begin by sending a start condition followed by the device address with the write bit set.
   • Send the memory address where writing should begin.
   • Transmit the data bytes to be written into memory.
   • End with a stop condition.

5. Reading Data:

   • Start with a write operation to send the desired memory address.
   • Follow with a repeated start and then the device address with the read bit set.
   • Receive the data bytes from the EEPROM.
   • End with a stop condition after all desired data is read.

6. Handling Write Operations:

   • Remember that each write cycle takes up to 5ms. Avoid initiating new writes until the previous one is complete to prevent data corruption.

7. Protecting Against Power Failures:

   • Implement safeguards in your design to ensure data integrity during unexpected power loss, especially during write operations.

8. Testing:

   • After assembly, test the EEPROM for correct operation under all expected conditions, including temperature extremes and varying supply voltages.
