These license terms are an agreement between you and Microsoft Corporation (or one of its affiliates). They apply to the software named above and any Microsoft services or software updates (except to the extent such services or updates are accompanied by new or additional terms, in which case those different terms apply prospectively and do not alter your or Microsoft’s rights relating to pre-updated software or services). IF YOU COMPLY WITH THESE LICENSE TERMS, YOU HAVE THE RIGHTS BELOW. BY USING THE SOFTWARE, YOU ACCEPT THESE TERMS.

  1. General. You may install and use the software and the included Microsoft applications solely for internal development, testing and evaluation purposes. Any distribution or production use requires a separate license as set forth in Section 2.

  2. Contributions. Microsoft welcomes contributions to this software. In the event that you make a contribution to this software you will be required to agree to a Contributor License Agreement (CLA) declaring that you have the right to, and actually do, grant Microsoft the rights to use your contribution. For details, visit

  3. Included Microsoft Applications. The software includes other Microsoft applications which are governed by the licenses embedded in or made available with those applications.

  4. Third Party Components. The software may include third party components with separate legal notices or governed by other agreements, as may be described within the software or in the ThirdPartyNotices file(s) accompanying the software.

  5. Competitive Benchmarking. If you are a direct competitor, and you access or use the software for purposes of competitive benchmarking, analysis, or intelligence gathering, you waive as against Microsoft, its subsidiaries, and its affiliated companies (including prospectively) any competitive use, access, and benchmarking test restrictions in the terms governing your software to the extent your terms of use are, or purport to be, more restrictive than Microsoft’s terms. If you do not waive any such purported restrictions in the terms governing your software, you are not allowed to access or use this software, and will not do so.

  1. DISTRIBUTION AND PRODUCTION USE. If you have obtained and/or are developing on microprocessor(s) and/or microcontroller(s) (“hardware”) listed in the file named “LICENSED-HARDWARE.txt” included in the repository and/or distributed with the software you have the following rights in and to the software solely when used in combination with the hardware. In the event hardware is not listed in the LICENSED-HARDWARE.txt file, you do not have the rights in this Section 2.
  1. Distribution and Production Use Rights.
  1. You may use the software in production (e.g. program the modified or unmodified software to devices you own or control) and distribute (i.e. make available to third parties) the modified or unmodified binary image produced from this code.

  2. You may permit your device distributors or developers to copy and distribute the binary image as programmed or to be programmed to your devices.

  3. You may redistribute the unmodified or modified source to your device distributors or developers. Modifications must be clearly marked. Any redistribution in source code form must contain this license and any other licenses that accompany the software.

  1. Requirements. For any code you distribute, you must:
  1. when distributed in binary form, except as embedded in a device, include with such distribution the terms of this agreement;

  2. when distributed in source code form to distributors or developers of your devices, include with such distribution the terms of this agreement; and

  3. indemnify, defend and hold harmless Microsoft from any claims, including attorneys’ fees, related to the distribution or use of your devices, except to the extent that any claim is based solely on the unmodified software.

  1. Restrictions. You may not:
  1. use or modify the software to create a competing real time operating system software;

  2. remove any copyright notices or licenses contained in the software;

  3. use Microsoft’s trademarks or trade dress in your application in any way that suggests your device or application comes from or is endorsed by Microsoft;

  4. transfer individual components, specific libraries, classes, functions or code fragments of the software separately for purposes unrelated to the software; or

  5. use or distribute the software in any way that would subject the software or Microsoft’s intellectual property or technology to any other license terms.

  1. SCOPE OF LICENSE. The software is licensed, not sold. Microsoft reserves all other rights. Unless applicable law gives you more rights despite this limitation, you will not (and have no right to):
  1. remove, minimize, block, or modify any notices of Microsoft or its suppliers in the software;

  2. use the software in any way that is against the law or to create or propagate malware; or

  3. share, publish, distribute, or lease the software (except as permitted in Section 2 above), or provide the software as a stand-alone offering for others to use.

  2. EXPORT RESTRICTIONS. You must comply with all domestic and international export laws and regulations that apply to the software, which include restrictions on destinations, end users, and end use. For further information on export restrictions, visit

  3. SUPPORT SERVICES. Microsoft is not obligated under this agreement to provide any support services for the software. Any support provided is “as is”, “with all faults”, and without warranty of any kind.

  4. UPDATES. Microsoft may periodically update the software. You may obtain updates only from Microsoft or Microsoft-authorized sources. Updates may not include or support all existing software features, services, or peripheral devices.

  5. TERMINATION. Without prejudice to any other rights, Microsoft may terminate this agreement if you fail to comply with any of its terms or conditions. In such event, you must destroy all copies of the software and all of its component parts.

  6. ENTIRE AGREEMENT. This agreement, and any other terms Microsoft may provide for supplements, updates, or third-party applications, is the entire agreement for the software. To the extent you have entered into a separate agreement with Microsoft relating specifically to the software, the terms in such agreement shall control.

  7. APPLICABLE LAW AND PLACE TO RESOLVE DISPUTES. If you acquired the software in the United States or Canada, the laws of the state or province where you live (or, if a business, where your principal place of business is located) govern the interpretation of this agreement, claims for its breach, and all other claims (including consumer protection, unfair competition, and tort claims), regardless of conflict of laws principles. If you acquired the software in any other country, its laws apply. If U.S. federal jurisdiction exists, you and Microsoft consent to exclusive jurisdiction and venue in the federal court in King County, Washington for all disputes heard in court. If not, you and Microsoft consent to exclusive jurisdiction and venue in the Superior Court of King County, Washington for all disputes heard in court.

  8. CONSUMER RIGHTS; REGIONAL VARIATIONS. This agreement describes certain legal rights. You may have other rights, including consumer rights, under the laws of your state or country. Separate and apart from your relationship with Microsoft, you may also have rights with respect to the party from which you acquired the software. This agreement does not change those other rights if the laws of your state or country do not permit it to do so. For example, if you acquired the software in one of the below regions, or mandatory country law applies, then the following provisions apply to you:

  1. Australia. You have statutory guarantees under the Australian Consumer Law and nothing in this agreement is intended to affect those rights.

  2. Germany and Austria.

  1. Warranty. The properly licensed software will perform substantially as described in any Microsoft materials that accompany the software. However, Microsoft gives no contractual guarantee in relation to the licensed software.

  2. Limitation of Liability. In case of intentional conduct, gross negligence, claims based on the Product Liability Act, as well as, in case of death or personal or physical injury, Microsoft is liable according to the statutory law.

Subject to the foregoing clause ii., Microsoft will only be liable for slight negligence if Microsoft is in breach of such material contractual obligations, the fulfillment of which facilitate the due performance of this agreement, the breach of which would endanger the purpose of this agreement and the compliance with which a party may constantly trust in (so-called “cardinal obligations”). In other cases of slight negligence, Microsoft will not be liable for slight negligence.



This limitation applies to (a) anything related to the software, services, content (including code) on third party Internet sites, or third party applications; and (b) claims for breach of contract, warranty, guarantee, or condition; strict liability, negligence, or other tort; or any other claim; in each case to the extent permitted by applicable law.

It also applies even if Microsoft knew or should have known about the possibility of the damages. The above limitation or exclusion may not apply to you because your state, province, or country may not allow the exclusion or limitation of incidental, consequential, or other damages.

Please note: As this software is distributed in Canada, some of the clauses in this agreement are provided below in French.

Remarque: Ce logiciel étant distribué au Canada, certaines des clauses dans ce contrat sont fournies ci-dessous en français.

EXONÉRATION DE GARANTIE. Le logiciel visé par une licence est offert « tel quel ». Toute utilisation de ce logiciel est à votre seule risque et péril. Microsoft n’accorde aucune autre garantie expresse. Vous pouvez bénéficier de droits additionnels en vertu du droit local sur la protection des consommateurs, que ce contrat ne peut modifier. La ou elles sont permises par le droit locale, les garanties implicites de qualité marchande, d’adéquation à un usage particulier et d’absence de contrefaçon sont exclues.

LIMITATION DES DOMMAGES-INTÉRÊTS ET EXCLUSION DE RESPONSABILITÉ POUR LES DOMMAGES. Vous pouvez obtenir de Microsoft et de ses fournisseurs une indemnisation en cas de dommages directs uniquement à hauteur de 5,00 $ US. Vous ne pouvez prétendre à aucune indemnisation pour les autres dommages, y compris les dommages spéciaux, indirects ou accessoires et pertes de bénéfices.

Cette limitation concerne:

•tout ce qui est relié au logiciel, aux services ou au contenu (y compris le code) figurant sur des sites Internet tiers ou dans des programmes tiers; et

•les réclamations au titre de violation de contrat ou de garantie, ou au titre de responsabilité stricte, de négligence ou d’une autre faute dans la limite autorisée par la loi en vigueur.

Elle s’applique également, même si Microsoft connaissait ou devrait connaître l’éventualité d’un tel dommage. Si votre pays n’autorise pas l’exclusion ou la limitation de responsabilité pour les dommages indirects, accessoires ou de quelque nature que ce soit, il se peut que la limitation ou l’exclusion ci-dessus ne s’appliquera pas à votre égard.

EFFET JURIDIQUE. Le présent contrat décrit certains droits juridiques. Vous pourriez avoir d’autres droits prévus par les lois de votre pays. Le présent contrat ne modifie pas les droits que vous confèrent les lois de votre pays si celles-ci ne le permettent pas.

SLA0047 Rev2/July 2020

Software license agreement


This is a legally enforceable contract (Agreement) between STMicroelectronics International N.V., Swiss branch and/or its affiliated companies (STMicroelectronics or ST) and you, on behalf of yourself, or on behalf of the entity by which you are employed and/or engaged (You).

Please indicate Your acceptance of this contract by selecting “I ACCEPT” or indicate Your rejection of this contract by selecting “I DO NOT ACCEPT” as indicated below in the media,




Licensed Software: means the software/firmware, examples, project template and all the related documentation and design tools licensed and delivered in the form of object and/or source code as the case may be.

Your Product: means Your and Your end-users’ product or system, and all the related documentation, that includes or works in combination with an executable version of the Licensed Software or derivative of the Licensed Software as permitted in this Agreement and provided further that such Licensed Software or derivative of the Licensed Software as permitted in this Agreement executes solely and exclusively on microcontroller devices manufactured by or for ST.


STMicroelectronics grants You a non-exclusive, worldwide, non-transferable (whether by assignment or otherwise unless expressly authorized by ST) non sub-licensable, revocable, royalty-free limited license of the Licensed Software to:

  1. use, make copies and prepare derivative works of Licensed Software that is delivered by ST in source code format for the sole purpose of designing, developing and manufacturing Your Products;

  2. use, make copies and prepare derivative works (without reverse engineering) of the Licensed Software that is delivered by ST in object code format for the sole purpose of designing, developing and manufacturing Your Products;

  3. make copies and prepare derivative works of the documentation part of the Licensed Software for the sole purpose of providing documentation for Your Products and their usage;

  4. make, have made, import, export and otherwise distribute the Licensed Software or derivative of the Licensed Software as permitted in this Agreement solely in object code format, as incorporated in Your Products, or for execution on Your Products, provided such distribution is subject to license terms as protective of the Licensed Software and ST’s rights in the Licensed Software as this Agreement (including without limitation a warranty disclaimer and a limitation of liability as protective of ST as those contained in this Agreement).


Title to the Licensed Software, related documentation and all copies thereof remain with ST and/or its licensors. You may not remove any copyright notice, warranty disclaimer, or other proprietary notice from the Licensed Software or from any permitted copies of the Licensed Software. You shall prevent any unauthorized copying of the Licensed Software, including without limitation any documentation parts.


Unless otherwise explicitly stated in this Agreement, You may not sell, assign, sublicense, lease, rent or otherwise distribute the Licensed Software for commercial purposes, in whole or in part.

You acknowledge and agree that any use, adaptation translation or transcription of the Licensed Software or any portion or derivative thereof, for use with processors manufactured by or for any entity other than ST is a material breach of this Agreement.

You shall not decompile the object code of the Licensed Software or otherwise reverse engineer the Licensed Software. You shall not use the Licensed Software as a basis to create similar or competing software or products.

You shall comply with all applicable laws and regulations affecting the use of the Licensed Software including any applicable export control law or regulation.

Neither the name nor any trademark of STMicroelectronics nor other contributors to the Licensed Software may be used to endorse or promote software or products derived from the Licensed Software (including any part thereof) without specific written permission.

No use, reproduction or redistribution of this Licensed Software partially or totally may be done in any manner that would subject this Licensed Software to any Open Source Terms (as defined below).


The Licensed Software may contain software subject to Open Source Terms (as defined below) applicable for each such portion (Open Source Software), as further specified in the Licensed Software. Such Open Source Software is supplied under the applicable Open Source Terms and is not subject to the terms and conditions of license hereunder. By installing copying, downloading, accessing or otherwise using the Licensed Software, You agree to be bound by such Open Source Terms with regard to such Open Source Software. Open Source Terms: mean any open source license which requires as part of distribution of software that the source code of such software is distributed therewith or otherwise made available, or open source license that substantially complies with the Open Source definition specified at and any other comparable open source license such as for example GNU General Public License (GPL), Eclipse Public License (EPL), Apache Software License, BSD license and MIT license.


Certain portions of the Licensed Software may be subject to third party license terms as expressly specified in the Licensed Software. In such event, those portions are supplied under the specified third party license terms and are not subject to the license terms of this Agreement. By installing copying, downloading, accessing or otherwise using the Licensed Software, You agree to be bound by such third party license terms with regard to those portions.


No rights or licenses are granted to You, except as expressly stated in this Agreement. Without limiting the generality of the foregoing, no rights or licenses are granted in any products, technology or intellectual property rights of ST except those embodied in the Licensed Software.


The Licensed Software is provided “as is” and “with all faults” without warranty of any kind expressed or implied. ST and its licensors expressly disclaim all warranties, expressed, implied or otherwise, including without limitation, warranties of merchantability, fitness for a particular purpose and non-infringement of intellectual property rights. ST does not warrant that the use in whole or in part of the Licensed Software will be interrupted or error free, will meet Your requirements, or will operate with the combination of hardware and software selected by You.

You are responsible for determining whether the Licensed Software will be suitable for your intended use or application or will achieve your intended results. ST will not be liable to You and/or to any third party for the derivative works of the Licensed Software developed by You.

ST has not authorised anyone to make any representation or warranty for the Licensed Software, and any technical, applications or design information or advice, quality characterization, reliability data or other services provided by ST shall not constitute any representation or warranty by ST or alter this disclaimer or warranty, and no additional obligations or liabilities beyond those explicitly stated in this Agreement shall arise from ST’s providing such information or services. ST does not assume or authorize any other person to assume for it any other liability in connection with the Licensed Software.

Nothing contained in this Agreement will be construed as:

  1. a warranty or representation by ST to maintain production of any ST device or other hardware or software with which the Licensed Software may be used or to otherwise maintain or support the Licensed Software in any manner; or

  2. a commitment from ST and/or its licensors to bring or prosecute actions or suits against third parties for infringement of any of the rights licensed hereby, or conferring any rights to bring or prosecute actions or suits against third parties for infringement. However, ST has the right to terminate this Agreement immediately upon receiving notice of any claim, suit or proceeding that alleges that the Licensed Software or Your use or distribution of the Licensed Software infringes any third party intellectual property rights.

All other warranties, conditions or other terms implied by law are excluded to the fullest extent permitted by law.


In no event shall ST or its licensors be liable to You or any third party for any indirect, special, consequential, incidental, punitive damages or other damages (including but not limited to, the cost of labor, re-qualification, delay, loss of profits, loss of revenues, loss of data, costs of procurement of substitute goods or services or the like) whether based on contract, tort, or any other legal theory, relating to or in connection with the Licensed Software, the documentation or this Agreement, even if ST has been advised of the possibility of such damages.

In no event shall ST’s liability to You or any third party under this Agreement, including any claim with respect of any third party intellectual property rights, for any cause of action exceed 100 US$. This section does not apply to the extent prohibited by law. For the purposes of this section, any liability of ST shall be treated in the aggregate.


ST may terminate this Agreement, including its licenses, at any time if You are in material breach of any of its terms and conditions and You have failed to cure such breach within 30 (thirty) days after receiving notification from ST of such breach. Upon termination, You will immediately destroy or return all copies of the Licensed Software (including without limitation any documentation) to ST. After termination, Your sole surviving right will be to continue to use the Licensed Software solely to the extent that it was already incorporated before Your material breach of this Agreement into Your Products, which were sold by You before the date of Your material breach.


This Agreement and matters connected with the validity, interpretation or performance thereof shall be governed, construed, interpreted, and applied in all respects by the law in place in Switzerland, without resort to conflict of laws principles. The Parties expressly agree that the United Nations Convention on Contracts for the International Sale of Goods shall not apply to this Agreement or to their relationship.

Dispute Resolution. The Parties consent to exclusive jurisdiction in the court of Canton of Geneva, Switzerland for purposes of any litigation arising from this Agreement. For the avoidance of doubt, nothing in this section shall prevent either Party seeking interim injunctive relief from a court or tribunal of appropriate jurisdiction.


If any provision of this agreement is or becomes, at any time or for any reason, unenforceable or invalid, no other provision of this agreement shall be affected thereby, and the remaining provisions of this agreement shall continue with the same force and effect as if such unenforceable or invalid provisions had not been inserted in this Agreement.


The failure or delay of either party to enforce any provision of this Agreement shall not operate or be construed as a waiver of any other or a subsequent breach of the same or a different provision.


This Agreement may not be assigned by You, nor any of Your rights or obligations hereunder, to any third party without prior written consent of ST. In the event that this Agreement is assigned effectively to a third party, this Agreement shall bind upon successors and assigns of the parties hereto.


Nothing in this Agreement shall create, or be deemed to create, a partnership or the relationship of principal and agent or employer and employee between the Parties. Neither Party has the authority or power to bind, to contract in the name of or to create a liability for the other in any way or for any purpose.
