High Quality Content by WIKIPEDIA articles! I C is a multi-master serial single-ended computer bus invented by Philips that is used to attach low-speed peripherals to a motherboard, embedded system, or cellphone. Since the mid 1990s several competitors (e.g. Siemens AG (later Infineon Technologies AG), NEC, Texas Instruments, STMicroelectronics (formerly SGS-Thomson), Motorola (later Freescale), Intersil, etc.) brought I C products on the market, which are fully compatible to the NXP (formerly Philips' semiconductor division) I C-system. As of October 1, 2006, no licensing fees are required to implement the I C protocol. However, fees are still required in order to have I C slave addresses allocated by NXP. SMBus is a subset of I C that defines stricter electrical and protocol conventions. One purpose of SMBus is to promote robustness and interoperability. Accordingly, modern I C systems incorporate policies and rules from SMBus, and the line between these two standards is often blurred in practice.
