Applications of I2C

I2C is a inter integrated circuit. It is a serial communication protocol used to connect with the low speed devices. Some of the application of I2c are

• Reading certain memory ICs
• Accessing DACs and ADCs
• Transmitting and controlling user-directed actions
• Reading hardware sensors
• Communicating with multiple micro-controller

Advantages of I2C

• I2C is half duplex communication
• It provides flexible data transmission rates.
• It provides long-distance communication than SPI.
• Each device on the bus is controlled independently.
• This protocol requires only two cables to communicate with slave devices.
• It can accommodate several master interactions through arbitration.

Disadvantages of I2C

• The complexity of hardware increases when no. of master or slave devices are high in the circuit.
• It provides a half-duplex mode for communication.
• Slower due to pull up concepts.
• Many devices have multiple addresses stored, which can cause conflicts.
