CAN FD BUS Protocol Stack: Details of the Software Architecture
CAN FD interface layer: It sits on top of the physical and data link layers of the CAN FD architecture. CAN FD interface layer is responsible for providing a standardized interface between the CAN FD controller and the application layer.
CAN FD Drivers: CAN FD drivers are responsible for providing an abstraction layer between the hardware and the software, allowing the application layer to communicate with the CAN FD bus without needing to know the details of the underlying hardware.

Configuration & Integration Support
Our CAN FD protocol software is designed to be fully configurable as per project specifications. We provide support for configuration of CAN FD Stack.
Support for After-market Solutions
Development, testing and maintenance support for after-Market products for Telematics, ADAS, remote vehicle diagnostic applications.
Ans. The modern vehicle manufacturers stipulate transmission of larger amounts of data at optimum rates across the vehicle network. And The Classical CAN BUS protocol supports the transfer of only up to 8 bytes of data.
Hence, there was a need for next generation CAN protocol. CAN FD (CAN with flexible data rate) vehicle network protocol has been designed to support up to 64 bytes of data transfer.
Following are the business use-cases of our CAN FD protocol stack:
- Telematics
- Powertrain
- Electric Vehicle powertrain
- Infotainment System
- Automotive ECU Re-programming
- ADAS
Ans. Our pre-tested CAN-FD stack solution consists of the following software services. The low level device drivers are platform dependent
- CAN-FD Device Drivers
- CAN-FD Network management layer
- CAN-FD Interface Layer
Ans. Yes we provide complete analysis, stack integration and maintenance support services as part of our Service Level Agreement (SLA).
Ans. We provide consultation to our customers for existing sequence of the CAN FD bootloader module.
However, we can also collaborate for development of the CAN FD bootloader solution based on the proposed bootloader design as per the project requirements.
Ans. Our CAN FD protocol software is compliant to ISO11898 standard.
Ans. The software source code is developed using embedded C in compliance with MISRA-C standard.
We adhere to software development best practices as per CMMI level 3 standards at the organization level.
Ans. In the CAN FD protocol software, the CAN FD Interface layer can be customized as per your project/application requirement.
Static configuration is provided for customizing Tx and Rx messages through Cfg.c and Cfg.h files.
Ans. As a technology partner, we have partnered with global OEMs’ and suppliers for integration of CAN FD protocol stack. Our CAN FD protocol stack has been Tested OK during several end-of-line testing and has been integrated with the production environments.

- What is CAN FD Protocol?
CAN Flexible Data is a CAN bus protocol that supports a data bit rate of up to 8 Mbps and a payload capacity of 64 bytes. It is an extension to Classical CAN or Classical CAN.
The ported J1939 stack consisted of J1939 Data Link and Transport Layer (J1939\21), Network Management layer (J1939/81), Vehicle Application Layer (J1939/71) and Vehicle Diagnostics Layer (J1939/73)
The role of software in automotive has become quite big and important. These applications need a lot of vehicle’s data and that too in real time. And this where CAN FD excels! Automotive OEMs plan to completely migrate from Classical CAN to CAN FD in the coming years.
- CAN vs CAN FD- Why industry felt the for a faster avatar of CAN?
Advanced automotive applications such as Telematics, EV Powertrain Management, Infotainment . require faster and larger data transfers. (Reason – the amount and type of real-time data that these applications deal with. For example, an infotainment system needs to display a gamut of vehicle information- tire pressure, door lock sensor info, transmission system info etc. at real-time).Classic CAN with its maximum data rate of 1 Kbps and a payload capacity of 8 bytes was not the right fit.These constraints paved the way for CAN FD protocol. CAN FD protocol software offers flexible data rates of up to 8 Mbps and a data payload capacity of 64 bytes.
- What is a CAN FD Controller and CAN FD Transceiver?
CAN FD controller is a hardware chip/platform that can be added to the host controller as a separate component or can be embedded inside it.
The CAN FD Controller is responsible for converting the messages in accordance with the CAN FD protocol.
The transceiver then transmits the messages over the Controller Area Network (CAN BUS). The CAN transceiver along with some other layers such as Transport Layer (ISO 15765) and Bootloader, together comprise of a CAN Stack.
