The full form of I2C is Inter-Integrated Circuit.
I2C (Inter-Integrated Circuit) is a serial communication protocol widely used in embedded systems for short-distance communication between integrated circuits. It utilizes two wires: Serial Data (SDA) and Serial Clock (SCL) to transmit data between a master device and one or more slave devices. Its simplicity and ease of implementation have made it a popular choice in various applications ranging from consumer electronics to industrial automation. Unlike SPI, which is another common serial communication protocol, I2C uses addressing to communicate with specific devices on the bus, allowing multiple devices to share the same two wires. This makes it efficient for applications where a microcontroller needs to communicate with several peripherals.
Here's a breakdown of key aspects:
- Inter: Indicates the connection between different integrated circuits.
- Integrated: Refers to the individual chips or components on a circuit board.
- Circuit: Denotes the electronic circuit itself, composed of these integrated components.
Therefore, I2C, in its full form, Inter-Integrated Circuit, directly describes its function: a communication protocol enabling data transfer between different integrated circuits within a system.
