LIN is a sub-network deployed in both passenger and off-road vehicles. Instead of paying the price for accurate hardware, it pays the price in time and soft-ware. LIN (LOCAL INTERCONNECT NETWORK) SOLUTIONS 2 LIN PRODUCTS A typical LIN node consists of a microcontroller for handling the LIN protocol and a LIN trans-ceiver for interfacing the digital part and the physical line (see Figure 5 . LIN bus topology). Figure 5. LIN (Local Interconnect Network) is a serial communications technology that was developed for cost-sensitive use areas in the automobile. This E-Learning module is intended for all those who want familiarity with LIN communication technology and understand it. LIN stands for Local Interconnect Network. LIN Frame consists of the two parts header and response. Target Group. The protocol includes an autobaud step on every The transceiver transmitter converts the logic level LIN protocol data stream on the TXD input into a VBAT level LIN bus signal using a current-limited, wave-shaping driver, which reduces electromagnetic emissions. The Local Interface Network bus, or LIN bus, is a single ended bus. LIN (Local Interconnect Network) is a serial network protocol used for communication between components in vehicles. The Single Wire Controller Area Network bus, or SWCAN bus, is a dedicated single ended bus. Lin: Local Interconnect network cheaper than CAN but is also slower. LIN Protocol and Physical Layer Requirements Because the whole idea of LIN is to be a simple, cost-effective communication interface, a dedicated communication controller is not implemented. It is a one wore communication. LIN bus topology 2.1 LIN MICROCONTROLLERS The latest version of LIN is LIN 2.0 and was released in 2003. Today, LIN bus is a de facto standard in practically all modern vehicles - with examples of automotive use cases below:. STMicroelectronics offers both kind of products. There are 2 main LIN families: LIN1 and LIN2.They are essentially differentiated by the way their messages are encoded. Rather a microcontroller is programmed with the LIN protocol, and used to drive the communication to the transceiver via the serial interface. This is a reliable and economical communication protocol allowing vehicle’s on-board computer to converse with its subsystems.. are usually handled by LIN network. The core of LIN is a serial network protocol controller and a physical layer transceiver. In 1998 a group of companies including Volvo, Motorola, Audi, BMW, Daimler Chrysler, and Volkswagen formed a consortium to develop LIN. ... • An optional Protocol Converter: • Converts Microcontroller signals into bus protocol signals, and visa versa. The Local Interconnect Network (LIN) bus was developed to create a standard for low-cost, low-end multiplexed communication in automotive networks. The Lin protocol (Local Interconnect Network) is a serial system bus used mainly in automotive industry meeting the standard ISO-17987. It is a one wore communication. Simpler functionalities like wiper, mirror control and washer etc. Unlike CAN, which is a broadcast protocol, LIN is a master/slave communication standard. What is Local Interconnect Network (LIN) BUS Protocol Stack? LIN bus applications. The need for a cheap serial network arose as the technologies and the facilities implemented in the car grew, while the CAN bus was too expensive to implement for every component in the car. LIN (Local Interconnect Network): History: LIN (Local Interconnect Network) was developed as cost-effective alternate to CAN protocol.
