I2C is a two-wire, bi-directional serial bus that provides a simple and efficient method of data transmission over a short distance between many devices. The DI2CM core provides an interface between a microprocessor / microcontroller and an I2C bus. It can work as a master transmitter or master receiver depending on working mode determined by microprocessor/microcontroller. The DI2CM core incorporates all features required by the latest I2C specification including clock synchronization, arbitration, multi-master systems and High-speed transmission mode. Built-in timer allows operation from a wide range of the clk frequencies.
DI2CM is a technology independent design that can be implemented in a variety of process technologies.
