Licensing

A valid ecRTOS license is required whenever ecRTOS source files or libraries are referenced during the build of a user’s application, even if no ecRTOS system calls are invoked directly by the application. ecRTOS licenses are available in three types:

User license

User License is limited by the number of authorized users. Once purchased for a given user count, it may be used for future development as long as the same processor family is used.

User counts can be selected or expanded according to development needs.
Higher user counts receive significant volume discounts.
Multiple-user license packs may be used only within a single development unit or department. License sharing across different units or departments is not permitted.

Project License

When the number of developers becomes large and a User License becomes less cost-effective, a Project License may be selected.

It is restricted to a single product development project, but unlimited in number of users or departments.
If derivative or improved products are built from a common source base, differing only in macro definitions or build settings, they are considered part of the same project.
Conversely, if the source code is split, maintained separately, or independently updated even for similar products using the same hardware, it is considered a different project.

Series License

When many product variations exist and a Project License becomes expensive, a Series License may be chosen.

It is restricted to a single product series, but unlimited in number of projects within that series.
Whether products belong to the same series is determined solely by the product-line designation shown in customer catalogs (e.g., “XXXX Series”).

Registration & Maintenance Terms

Order Registration & Shipping

User registration is completed prior to shipment. The registered information will be printed and included with your Software User License Agreement.

When placing an order, please provide the complete details of the managing authority, including the full department and section names. For Project Licenses, the following additional information is required:

Project Details: Product name and development code.
Target processor Specifications: Target processor manufacturer and CPU part number.

Maintenance Service & Fees

The initial purchase price includes one year of maintenance (technical support and software upgrades). Annual fees for subsequent years are structured as follows:.

Number of Users	Annual Fee
1 User	200 USD
2 Users	300 USD
3 Users	400 USD
4 Users	500 USD
5 users and above	600 USD
Series license	600 USD

Maintenance Policies

Renewal Discount: A 10% discount is applied to the annual fee if the maintenance is renewed continuously without interruption.
Project License Benefit: For project-based licenses, the maintenance period may be extended free of charge until the project development is complete.
