I²C (Inter-Integrated Circuit) is a serial communication bus that allows communication between a single master and multiple slaves. Developed by Philips (now NXP Semiconductors), this protocol provides a simple yet efficient communication method and is widely used to transfer data between electronic components such as sensors, microcontrollers, and memory modules.
Key features of I²C
Two lines:
SDA (Serial Data Line): A line for data transmission.
SCL (Serial Clock Line): A line for transmitting clock signals.
These two wires are connected by a pull-up resistor, so all devices in the system share the wire.
Multimaster and multislave support:
Communication between multiple masters and multiple slave devices is possible, with each device having a unique address.
Addressing:
I²C devices can use 7-bit or 10-bit addresses. The 7-bit address scheme supports up to 128 unique devices.
speed:
Standard Mode: Up to 100 kbps.
Fast Mode: Up to 400 kbps.
Fast Mode Plus: Up to 1 Mbps.
High-Speed Mode: Up to 3.4 Mbps.
