Instructions for Use:

1. Power Supply Connection:

   • Connect VCC to a supply voltage between 2.7V and 5.5V.
   • Connect GND to the ground.

2. I2C Interface Setup:

   • Ensure SDA and SCL lines are connected to pull-up resistors to VCC.
   • Set up the microcontroller or host system to communicate over the I2C bus at standard mode speeds (up to 100kHz) or fast mode speeds (up to 400kHz).

3. Address Configuration:

   • Configure the device address by setting the address pins A0 and A1 as required. Refer to the datasheet for specific address configurations.

4. Memory Operations:

   • To write data, initiate an I2C start condition followed by the device write command and address, then send the data bytes.
   • To read data, initiate an I2C start condition followed by the device read command and address, then read the data bytes.

5. Nonvolatile Writes:

   • Ensure that the write cycle time of 10ms is observed to guarantee data integrity in the EEPROM memory.

6. Operating Temperature:

   • Operate the device within the temperature range of -40掳C to +85掳C to ensure reliable performance.

7. Handling Precautions:

   • Handle the device with care to avoid electrostatic discharge (ESD) damage.
   • Follow proper soldering practices when mounting on a PCB.
