Excellent I2C core for Altera, Xilinx and PLDs for $50.00. Im a FPGA designer and wacked off about two weeks from developing my own I2C interface. The great thing about the product was that unlike alot of the other I2C cores I tried the darn thing fit in an already 90% full Altera 7256 and worked great in interfacing to the slave PLD devices. This is the kind of core you can put in the smallest Xilinx or Altera family PLD and have a cheap interface from any microprocessor-microcontroller to all your I2C slave parts through simple registers. It will keep your microcontroller from being bogged down doing the I2C operation via software. Or you can integrate the whole thing in you larger FPGA design. The great part is that Im a consulting engineer and I can reuse the code without repaying for license fees of the I2C core I bought, and there is no per product royalty for using it.
