I2C interface is a serial communication protocol, also known as Inter Integrated Circuit, which refers to the bus between integrated circuits. It is a two wire serial communication bus developed by Philips, which uses a multi master slave architecture and is mainly used to connect microcontrollers and other peripheral devices, such as sensors, memory, displays, etc.
The control method is simple, the device packaging is small, and the communication speed is high. It transfers information between devices connected to the bus through serial data (SDA) lines and serial clock (SCL) lines. Each device has a unique address recognition and can serve as a transmitter or receiver. The I2C interface is widely used in the field of microelectronic communication control, with a standard transmission rate of 100Kbit/s and a maximum transmission rate of up to 400Kbit/s. The simplification of hardware has reduced the pressure on chip designers to save output pins, bringing many benefits to chip applications such as cost reduction, reduced space, convenient testing, and easy upgrading.
Overall, the I2C interface provides an efficient and convenient way for communication between microcontrollers and their peripheral devices, and is one of the important bus standards in the field of microelectronic communication control.
