CAD/CAE Schematic Footprints and Symbols
Silicon Labs offers Ultra Librarian schematic symbols and PCB footprints for Silicon Labs’ products. Both PCB footprints and schematic symbols are available for download in a vendor neutral format which can then be exported to the leading EDA CAD/CAE design tools using the Ultra Librarian Free Reader. The Ultra Librarian software is a free downloadable reader which allows the user to view the '.bxl' files. It also allows you to export these symbols and footprints to other CAD tools using the Ultra Librarian software. These parametric data components allow you to reliably create consistent CAD entities to an established standard with minimal effort and significant time savings.
Note: These .bxl files are provided as-is to assist you in your designs. Silicon Labs makes no warranty or guarantee regarding their use. You must verify the results of the file export against the published data sheet prior to building your board.
