Inter-IC Bus (I2C)

 

 

The Inter-IC bus (I2C) is a two-wire serial bus designed by Phillips that provides a communications link between integrated circuits. Inter-IC buses are used to control and monitor applications in communications, computer, and industrial settings. Physically, the bus consists of two active wires and a ground connection. The active wires, the serial data line (SDA) and the serial clock line (SCL), are both bidirectional. Each component that is connected to the bus has a unique address and can, depending on its functionality, receive and/or transmit information. I²Cs (pronounced "Eye Squared C") are inexpensive interconnection chips and are therefore popular on circuit boards

Products & Services
Microcontrollers (MCU) are complete computer systems on a chip. They combine an arithmetic logic unit (ALU), memory, timer/counters, serial port, input/output (I/O) ports and a clock oscillator. Search by Specification | Learn more about Microcontrollers (MCU)
Digital signal processors (DSPs) are specialized microprocessors designed specifically for digital signal processing, usually in real-time. DSPs can also be used to perform general-purpose computations, but are not optimized for this function. Search by Specification | Learn more about Digital Signal Processors (DSP)
Microprocessor chips (MPU) are silicon devices that serve as the central processing unit (CPU) in computers. They contain thousands of electronic components and use a collection of machine instructions to perform mathematical operations and move data from one memory location to another.
