It is widely used for attaching lower-speed peripheral ICs to processors and microcontrollers in short-distance, intra-board communication. I 2C ( Inter-Integrated Circuit, eye-squared- C), alternatively known as I2C or IIC, is a synchronous, multi-master/multi-slave (controller/target), packet switched, single-ended, serial communication bus invented in 1982 by Philips Semiconductors. Philips Semiconductor, known today as NXP SemiconductorsĠ.1, 0.4, 1.0, 3.4 or 5.0 Mbit/s depending on mode
