IBUS, short for "Inter-Integrated Circuit (I2C) Bus," is a communication protocol that allows multiple electronic devices to communicate and share data with each other. It is a widely used serial bus system that enables communication between microcontrollers, sensors, and various other peripheral devices. The IBUS protocol was initially developed by Philips Semiconductors (now NXP Semiconductors) in the early 1980s.
The IBUS protocol operates using two communication lines, namely the Serial Data Line (SDA) and the Serial Clock Line (SCL). These lines are used to transmit and receive data bits between the devices connected to the bus. IBUS utilizes a master-slave architecture, where one device acts as the master and initiates the communication, while other devices act as slaves and respond to the master's requests.
IBUS supports multiple devices on the same bus, each having a unique address which allows the master to select and communicate with specific devices. The communication on the IBUS is bidirectional, enabling both read and write operations.
The protocol also incorporates various advanced features such as clock synchronization, data arbitration, and multi-master capability, which ensures efficient and reliable communication between devices.
Due to its simplicity, flexibility, and low power requirements, the IBUS protocol has become widely used in a variety of applications, including consumer electronics, automotive industry, industrial automation, and more.
