I2C Bus Interface - Master

Overview

The I2C is a two-wire, bi-directional serial bus, that provides a simple and efficient method of short distance data transmission between many devices. The DI2CM core provides an interface between a microprocessor/microcontroller and the I2C bus. It can work as a master transmitter or a master receiver - depending on a working mode, determined by the 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.
The DI2CM is a technology independent design, that can be implemented in a variety of process technologies.
