SAE J2602 Based LIN 2.1 Protocol Stack
Business Model of our Local Interconnect Network (LIN) Protocol Stack: Know the Value-Adds
Our LIN 2.1 Protocol Stack Solution (SAE J2602) is available under a one-time licensing fee model. This engagement model entitles you to leverage the following benefits:
- You own the source code of the LIN Bus Protocol Stack
- You can also benefit from the ownership of the IP rights
- As the owner of the IP Rights, your business can deploy this LIN Bus Protocol Stack solution across multiple production programs
We offer separate LIN protocol stack solutions for LIN Master and LIN Slave.

FAQs About LIN Bus Protocol Stack Solution
Ans. The layered architecture of our LIN Protocol stack includes:
- Low-level drivers (LIN, MCU, EEP, IVT, Timer)
- LIN Bus Protocol Stack (LIN Network Management and LIN Interface)
- LIN TP Layer
- UDS Stack (ISO 14229)
- Application Layer
The Bootloader includes:
- Bootloader Application
- UDS (ISO14229) Based Bootloader
Ans. LIN Drivers are developed for the specific microcontroller used in the automotive application. All other modules of the LIN Bus software stack are hardware agnostics.
We have expertise in developing LIN drivers for all the widely used MCU families. This includes Renesas, TI, Fujistsu and others.
Ans. Our automotive team has delivered several LIN bus protocol stack projects to customers from across US, Europe and India.
We can share the detailed case studies of the projects and related information, once we sign the Non-disclosure agreement.
Ans. Yes. As per our Service Level Agreement (SLA) for the LIN bus protocol Stack, we will provide the software configuration and integration services, along with the LIN bus software stack license.
The integration and configuration services will take care of both low-level drivers as well as the application-level integration.
Ans. We perform various tests in the course of LIN software stack development. Prior to the final project delivery, our LIN bus protocol stack solution undergoes the following testing procedures:
- Unit level Testing
- Functional Testing
- Data Link Layer Compliance testing, using Vector Testing Tools
Ans. Whether to use the manual method or the PC based tool, for the conversion from LDF file to configuration file code, will depend on the size of the file.
If there are considerable numbers of Tx and Rx messages for configuration, we will prefer to use our proprietary PC based auto-code generator tool.
Ans. Our LIN bus software stack is light-weight in size. The size of flash memory is 6 kB and RAM size is 1 kB. The RAM size could go higher depending on the size of the configuration file.
Ans. Yes, Our LIN bus protocol stack is completely modular. There are no global variables exchange between the programs files and every functionality is invoked with the help of specific APIs.
Modularity makes the LIN software stack light-weight and also easy to deploy in number of production programs, without any compatibility issue.
Ans. We offer separate stack solutions for both LIN Master and LIN slave. As LIN is not a broadcast protocol, the LIN master is tasked to initiate the command and the slave has to act on it.
Depending on the project specifications, we will deliver LIN master, LIN slave or both.
Ans. Yes, High-Level Design Document and Low-Level Design Document, will be a part of the LIN bus software stack package. In addition to that, we will also provide Functional Test Plan & Report and MISRA compliance Report.
These documents contain every detail you may need to make some enhancements to the stacks or to integrate the stack solution in multiple production projects.
