![]() ![]() Several competitors, such as Siemens, NEC, Texas Instruments, STMicroelectronics, Motorola, Nordic Semiconductor and Intersil, have introduced compatible I 2C products to the market since the mid-1990s. 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-controller/multi-target, packet switched, single-ended, serial communication bus invented in 1982 by Philips Semiconductors.
