DI2CM-FIFO

DI2CM-FIFO bridge to APB, AHB, AXI bus, this core provides an interface between a microprocessor/microcontroller and I2C bus. It can work as:

• a master transmitter or
• master receiver

depending on a working mode determined by the microprocessor/microcontroller. The DI2CM-FIFO core incorporates all features required by the latest I2C specification, including clock synchronization, arbitration, multi-master systems, and high-speed transmission mode. The built-in timer allows operation from a wide range of clk frequencies. The DI2CM-FIFO is a technology-independent design that can be implemented in a variety of process technologies.
