DI2CM – 12 years a slave… master

Digital Core Design, IP Core provider and a System-on-Chip design laboratories from Poland, introduced soft IP Core, targeting I2C design needs. The DI2CM core provides an interface between a microprocessor or microcontroller and the I2C bus. It can work as a master transmitter or master receiver - depending on a working mode, determined by the microcontroller. This universal solution is available with various system interface wrappers like AMBA - APB Bus, Altera Avalon Bus, Xilinx OPB Bus.

Poland, Bytom, 5th of March 2015.  Saying that the I2C is a two-wire, bi-directional serial bus, which provides simple and efficient method of short distance data transmission between many devices, is quite obvious. But still, reality shows that the I2C bus can be very confusing, and not only for the newcomers.

The DI2CM core provides an interface between a microprocessor or microcontroller and the I2C bus. It can work as a master transmitter or a  master receiver. It only depends on a working mode, determined by the microprocessor or microcontroller. - The DI2CM core incorporates all features required by the latest I2C specification – explains Piotr Kandora, R&D Director at Digital Core Design – this includes clock synchronization, 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, that’s why like all other company’s IP Cores, it can be implemented in a variety of process technologies.

Information about Digital Core Design:

The company founded in 1999, since the beginning stands in the forefront of the IP Core market. High specialization and profound customer service enabled to introduce more than 70 different architectures. Among them is the world’s fastest 8051 IP Core, the DQ80251, which is more than 66 times faster than the standard solution. As an effect, over 300 hundred licensees have been sold to more than 500 companies worldwide. Among them are the biggest enterprises like e.g. Sony, Siemens, General Electric and Toyota. But a lot of DCD’s customers are small businesses, R&D laboratories or front/back end offices, which require exact solution tailored to their project needs. Rough estimations say that more than 270 000 000 devices around the globe have been based on Digital Core Design’s IP Cores.
