We collaborated with Accelerated Designs, Inc. to provide schematic symbols and PCB footprints in a vendor-neutral format for our products. Footprints generated by Ultra Librarian® are based on the IPC-7351 specification, so you can create consistent-quality CAD entities with minimal effort. They can be customized and downloaded using the online version of Ultra Librarian Reader that we have integrated into many of our product pages.

Ultra Librarian 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. It is owned and licensed to you by Accelerated Designs, Inc. and its suppliers subject to the terms of the agreement accompanying the Ultra Librarian Installer Program. Access to the Ultra Librarian Reader is provided for your convenience, “as is," without any express or implied warranties from Microchip of any kind. Further, your use of the information, documents and downloads on this web page are governed by Microchip’s Website Terms and Conditions which can be found under the “Legal” link below or the third-party supplier’s license, as applicable.
