After last week’s CAN transceiver here’s another automotive click with a Microchip chip on it. This time it’s a LIN transceiver: MCP2003B click.

MCP2003B click

LIN stands for Local Interconnect Network. It’s an automotive standard used in conjunction with CAN. In fact LIN was invented to meet the demands of the growing complexity of vehicle electronics. CAN was becoming too expensive for extensive sensor networks inside a modern car. LIN is more cost-effective for simple sensor networks. Up to 15 slaves can be connected to one Master. The Master can, in turn, be a part of a larger CAN network.

To connect the transceiver on MCP2003B click to other LIN nodes or masters, the board has screw terminals for three wires: LIN, GND, and VBB, which is for bringing a sufficient supply voltage (between 5.5V and 30V according to the data sheet)

Like CAN, the robustness of LIN makes it suitable for industrial applications, not just automotive.

Our firmware team wrote a nice article about LIN if you are new to it. Otherwise you can dive right into development. Relevant details and links are on the product page. For the code, go straight to Libstock.

Yours sincerely,
