Description

NXP I2C-bus solutions. The I2C-bus revolutionized chip-to-chip communications by replacing complex parallel interfaces with a straightforward yet powerful serial structure. Invented by NXP (Philips) more than 30 years ago, the I2C-bus uses a simple two-wire format to carry data one bit at a time. It performs inter-chip addressing, selection, control, and data transfer. The I2C-bus devices are available in a wide range of functions and each slave device has its own I2C-bus address, selectable using address pins set high (1) or low (0). There can be multiple devices on the same bus, and more than one IC can act as master. The master role is typically played by a microcontroller.
