Instructions for Using AT24C01C-SSHM-T

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 1.8V to 5.5V.
   • Connect the ground (GND) pin to the system ground.

2. I2C Communication:

   • The device uses the I2C protocol for communication.
   • Connect the SDA (Serial Data) and SCL (Serial Clock) pins to the corresponding lines on the I2C bus.
   • Use pull-up resistors on both SDA and SCL lines to Vcc, typically 4.7kΩ.

3. Addressing:

   • The device has a 7-bit I2C address, which can be configured using the A0, A1, and A2 pins. Refer to the datasheet for specific address configurations.

4. Write Operation:

   • Start the I2C transaction by sending a start condition.
   • Send the 7-bit device address followed by a write bit (0).
   • Send the memory address where the data will be written.
   • Send the data byte(s) to be written.
   • Send a stop condition to complete the write operation.
   • Wait for the write time (tWR) to ensure the data is properly stored.

5. Read Operation:

   • Start the I2C transaction by sending a start condition.
   • Send the 7-bit device address followed by a write bit (0).
   • Send the memory address from which data will be read.
   • Send a repeated start condition.
   • Send the 7-bit device address followed by a read bit (1).
   • Read the data byte(s) from the device.
   • Send an acknowledgment (ACK) for each byte except the last one.
   • Send a not-acknowledge (NACK) after the last byte to indicate the end of the read.
   • Send a stop condition to complete the read operation.

6. Standby Mode:

   • To minimize power consumption, the device automatically enters standby mode when not in use.
   • The standby current is very low, typically between 0.1μA and 1μA.

7. Endurance and Data Retention:

   • The device supports up to 1,000,000 write/erase cycles.
   • Data retention is guaranteed for at least 100 years under normal operating conditions.

8. Handling and Storage:

   • Store the device in a dry, cool place to avoid damage.
   • Handle with care to prevent static discharge, which can damage the device.

For detailed information and specific timing diagrams, refer to the official datasheet provided by the manufacturer.
