Efficiently send and receive large quantities of data
Due to the increasing demand for data exchange in modern vehicles, the automotive industry has implemented a range of networks that efficiently send and receive large quantities of data. These include protocols such as CAN (Controller Area Network) and LIN (Local Interconnect Network) bus systems.
As the future of the industry develops, vehicles will include more ECUs that build on these types of in-vehicle connectivity. Therefore, the importance of in-vehicle networking (IVN) devices will grow with increasing quantities of data exchanged between ECUs and of course, the extended number of ECUs itself. As a result, the automotive industry established automotive networking systems such as the CAN FD (Flexible Data-rate) and CAN PN (Partial Networking) protocols for improved energy efficiency, and very recently the CAN FD SIC with Signal Improvement Capability which boosts CAN communications up to a speed of 8 Mbps.
Designed to meet and exceed the latest ESD and EMC requirements
Infineon offers a broad product portfolio of automotive transceivers for different bus segments, all of which are perfectly suited for the challenging automotive environments and are designed to meet and exceed the latest ESD and EMC requirements.
Depending on the respective vehicle network architecture and the related ECU supply path, different transceiver types are used. Infineon's automotive transceivers ensure reliable in-vehicle connectivity and communication, helping to minimize the current consumption and the related CO2 emissions at the vehicle level. Infineon's automotive transceiver products provide the best value through high performance, robust manufacture, and reliability.
Differences between automotive CAN and LIN protocols
The Infineon portfolio includes a range of different types of automotive transceivers centered around LIN and CAN protocols. The differences between the two protocols are the speeds of communication. LIN is used in low-speed applications while CAN is used in medium-speed applications.
Having said this, each of the protocols complements one another when used within in-vehicle networks, helping to connect all types of vehicle systems, as well as peripheral devices. For example, while CAN is ideal for use with error-sensitive systems on a 5 V differential, LIN is used within applications with low-bandwidth requirements on a 12 V single-wire bus.
Key features include:
- Products supporting network speed from 20 kbps (LIN) up to 8 Mbps (CAN FD SIC)
- Lowest current consumption in the market with CAN PN
- Endurance CAN family with Tambient -40 to +150°C
- Automotive transceiver family concept: variants are backward-compatible;
- pinto-pin compatibility with existing competitor's devices reduce development time and effort
- Outstanding ESD robustness
- Excellent EMC performance
- Low quiescent currents
- Worldwide OEM approval
- Highest quality
Durable and robust automotive CAN transceivers
Initially, the CAN technology was invented to offer robust and scalable networks in the car. With faster data rates, it turned out to be more difficult to keep this robustness. Developing complex networks with low data rates (500 kbps or 1 Mbps) was comparatively easier. Faster networks using 2 Mbps or 5 Mbps could be realized only in smaller and less complex networks. Modern networks require high data rates in stable networks. Such signal integrity can be granted with the newly developed CAN SIC Transceivers.
CAN FD SIC actively improves CAN signals to ensure robust communication in large networks and at faster bit rates. Signal ringing, an artifact of large, complex networks with unterminated stubs, are dramatically reduced, removing previous limitations in network topologies. Even lower specification cabling solutions can be considered.
Our range of automotive CAN transceivers provides durable and robust design made for challenging automotive applications and meets or exceeds the latest ESD and EMC requirements.
Automotive LIN transceivers designed to meet industry challenges
The LIN automotive protocol was developed to deliver low-speed data transfer rates over a single wire, allowing the implementation of cheap and efficient hardware-nodes within vehicles. The CAN bus has generally been viewed as too costly to run all in-vehicle network components, and so the LIN bus was developed to deliver standardized simpler systems and provide greater compatibility in tandem with CAN.
This means that serial network connections between actuators, sensors or switches, and an ECU can be designed efficiently and at lower costs for vehicle manufactures, allowing other protocols to manage more sensitive operations.
Infineon’s automotive LIN transceivers meet or exceed the latest ESD and EMC requirements and are designed to meet the challenges of the automotive industry.
Higher response time with automotive CXPI transceivers
Built to succeed the popular LIN protocols, CXPI (Clock eXtension Peripheral Interface) reduces material costs during manufacturing and lowers fuel consumption in vehicles by requiring fewer wire harnesses. This is done by integrating the CSMA/CR system (event initiate system) into the polling system of LIN. This ensures higher response time and scalability, and significantly reduces HMI and development costs, as well as reduces the number of the parts needed for the clock side of the design. Additionally, reliability is improved by cross-communication between slaves, a secondary clock master function, and CRC.
Our CXPI transceivers improve in-vehicle connectivity through reliable, low-noise components made for the automotive industry.
