DI2CMS - I2C Bus Interface - Master/Slave Description:
Overview
I2C is a two-wire, bi-directional serial bus that provides a simple and efficient method of data transmission over a short distance between many devices. The DI2CMS core provides an interface between a microprocessor / microcontroller and an I2C bus. It can work as a master or slave transmitter/receiver depending on working mode determined by microprocessor/microcontroller. The DI2CMS core incorporates all features required by the latest I2C specification including clock synchronization, arbitration, multi-master systems and 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 a technology independent VHDL or VERILOG design that can be implemented in a variety of process technologies and can be fully customized accordingly to customer needs.
DI2CMS is delivered with fully automated testbench and complete set of tests allowing easy package validation at each stage of SoC design flow.
