DI2CMS - I2C Bus Interface - Master/Slave
Block Diagram

Overview
The I2C is a two-wire, bi-directional serial bus, which provides a simple and efficient method of short distance data transmission between many devices. The DI2CMS core provides an interface between a microprocessor/microcontroller and an I2C bus. It can work as a master or a slave transmitter/receiver - depending on a working mode, determined by the microprocessor/microcontroller. The DI2CMS core incorporates all features required by the latest I2C specification, including clock synchronization, arbitration, multi-master systems and a high-speed transmission mode (the DI2CMS supports all the transmission speed modes). Built-in timer allows operation from a wide range of the clk frequencies. The DI2CMS is technology independent, that's why a VHDL or VERILOG design can be implemented in a variety of process technologies. Furthermore, it can be also completely customized in accordance to the customer's needs.The DI2CMS is delivered with fully automated testbench and complete set of tests
