List of compatible LIN chips #16

Open daxliniere opened 2 months ago

daxliniere commented 2 months ago

Hey @unreality, I've been having trouble finding the MCP2025 IC at a reasonable price in the UK and it got me thinking that it would be great to have a list of all the known compatible ICs for this project. Mostly CANBUS ICs show up.

MCP2025 ATA663211 MCP2002A MCP2002B TJA1027T (no built-in voltage regulator

I have also found units on AliExpress that use TJA1020/TJA1021 for a few bucks. Any idea on their suitability? https://www.mouser.co.uk/new/nxp-semiconductors/nxp-tja1021-transceivers/

Do you know of any others?

All the best, Dax.

You can use TJA1027T

Ive not tested anything except the MCP2025-330 and MCP2003 , but i'm reasonably confident any LIN transceiver will work. The only reason the MCP2025 was chosen to test with was that its a through-hole mount component that was available at the time.
