Car Manufacturers Ruined a Serial Communication Protocol
MuhScopeBroke:
CAN has gone to the wind now that you can't source the IC necessary to interface with it. Most of my companies serial communication has now moved towards I2C/DI2C in light of this but some older parts still use CAN and its been impossible to find components. Very tough on us little guys who just need a simple CAN transceiver
Scrts:
As of now:
TJA1041 - 2492 @ Digikey
TJA1043 - 145 @ Digikey
TJA1046 - 5875 @ Digikey
TJA1054 - 13472 @ Digikey
I did not check TI or Infineon PNs... Did not check Mouser or Newark...
Maybe buy in advance now?

You’re whining that car manufacturers “ruined” a bus standard designed by an auto parts supplier expressly for use in vehicles? :-DD
