The LIN Short Story • Targeted to be a lower performance (up to 20 kBit/s) • • • • • more cost effective solution than CAN LIN is based on SCI / UART to help minimize system cost. Communication rates up to 20kbps Up to 15 slave-LIN nodes per Master Can significantly reduce wiring cost & weight Wiring = 3 Wires (Power + Ground + LIN data) • Freescale is the only semiconductor company to be a founding member of the LIN consortium • Freescale products available TODAY: > > > > > Specific LIN Microcontroller Family Master and Slave MCU’s.

LIN was designed to be a low-performance, low-cost network -- lower cost than CAN networks and lower speed and lower performance than CAN. It's based around a standard SCI or UART hardware to help minimize the costs. Communications are 20kbps or slower and up to 15 slave nodes can be on any given LIN network with one single master. LIN can help significantly reduce the wiring costs and weight. A single wire is used for the LIN communications, combined with a battery level voltage supply and ground wire pair. Freescale is the only semiconductor company that is part of the founding membership of LIN. Consequently, we have the ability to vote on, and participate in, the design of the specifications. Freescale also has a wide variety of products available to create LIN nodes: Everything from microcontrollers to physical layers, including system-basis chips and integrated products. 3
