Instructions for Use

1. Power Supply: Ensure the supply voltage (VCC) is within the specified operating voltage range of 1.8V to 5.5V.

2. Communication Setup:

   • Connect the SDA and SCL lines to your microcontroller or host device.
   • Ensure proper pull-up resistors are used on both SDA and SCL lines for reliable I2C communication.

3. Address Configuration:

   • The device has a fixed I2C address if no address pins are available. Check the datasheet for the specific address.
   • If address pins are available, configure them according to the desired I2C address.

4. Write Operation:

   • Start by sending a start condition followed by the device address with the write bit set.
   • Send the memory address where the data will be written.
   • Transmit the data byte(s) to be written.
   • Finish with a stop condition.
   • Wait for the write cycle time (5ms) before performing another write or read operation.

5. Read Operation:

   • Send a start condition followed by the device address with the write bit set.
   • Send the memory address from which data will be read.
   • Send a repeated start condition followed by the device address with the read bit set.
   • Read the data byte(s).
   • Send an acknowledge (ACK) after each byte except the last one, followed by a not-acknowledge (NACK) and a stop condition.

6. Storage and Handling:

   • Store the device within the specified temperature range to ensure long-term reliability.
   • Handle with care to avoid damage from electrostatic discharge (ESD).

7. Endurance and Data Retention:

   • Be mindful of the endurance cycles and data retention limits when planning applications that require frequent writes or long-term data storage.
