Development Tools
CAD/CAE Symbols
Microchip and Accelerated Designs Inc. have collaborated together to provide Microchip customers with schematic symbols and PCB footprints for Microchip 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 Reader. The reader is available for free download below. Learn more about the Ultra Librarian.
The UL Reader is a subset of the Ultra Librarian toolset that can generate, import, and export components and their attributes in virtually any EDA CAD/CAE format. Footprints generated by the UL Reader are based on the IPC-7351 specification. In addition, the components (both symbol and footprint) can be modified to meet a user-defined standard using a purchased upgrade to the Ultra Librarian. Learn more about upgrading.

Providing components based on parametric data through the Ultra Librarian Reader will allow Microchip customers to reliably create consistent quality CAD entities to an established standard with minimal effort. It is anticipated that this free download
service will save Microchip's customers significant time.
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 in to other
CAD tools using the Ultra Librarian software.
