    I2C Master / Slave Controller IP

    OverviewFeaturesRequest Datasheet

    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 I2C bus. It can work as a master or 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 transmission speed modes). Built-in timer allows operation from wide range of clk frequencies. The DI2CMS is technology independent, so either VHDL or VERILOG design can be implemented in variety of process technologies. Furthermore, it can be also completely customized in accordance to your needs. The DI2CMS is delivered with fully automated test bench and complete set of tests, allowing easy package validation at each stage of SoC design flow.
