LD FPGA Module

If you have a embedded application where you need a microprocessor and programmable logic (FPGA). Now you do not need two chips any more you can put it all inside the FPGA. To make your on system on FPGA based on Logic Development platform you should just use the simple recipe.

Take a FPGA add a SDRAM and Flash and pour it together on a PCB and add some circuits and IC on your own choice.

Now you have a solution with a 32bit RISC (Xilinx MicroBlaze) connected directly to your custom FPGA part. This make the solution fit your exact requirements and not the other way around.

• Very flexible solution where it possible to make changes, upgrades and bug fixes to both the hardware and software without PCB update.
• The FPGA’s is made from latest IC technology, in conjunction to typical off the shelf micro controllers which is 1-2 generations behind.
• Possible to get all components with industrial temperature grade (-30degC - +85degC)
• Possible to fit the FPGA family/size and memory size. Also easy to change up and down.
• Standard low cost memories. Many different manufactories, sizes etc. No struggling with fitting the software in some internal RAM or Flash – there is a lot.
