Industry Information Dispatch: Is I2C Being Replaced?

by

(Source: Chip Interfaces ApS)Invented by Philips Semiconductors (now NXP Semiconductors) in 1980, the I2C (Inter-Integrated Circuit) bus made significant strides in simplifying communication in embedded systems. It is a simple two-wire interface used for synchronous, multi-master/multi-slave, single-ended serial communication.Forty-five years later, it is still widely used to connect low-speed peripheral integrated circuits (ICs), processors, and … Read more
