It only depends on a working mode, determined by the MCU or MPU. The DI2CM core incorporates all features required by the latest I2C specification, including clock synchronisation, clock stretch, arbitration, multi-master systems and high-speed transmission mode. The DI2CM IP Core has also been equipped with built-in timer, which allows operation for a wide range of clk frequencies.
DCD’s latest solution is a technology independent design, allowing it to be implemented in a variety of process technologies.
