Hey Guys, i have a board "820 2850-A" with a smc problem but Only have a "820 2915-B" to replace the SMC.. Can i replace a SMC from "820 2915-A" in a "820 2850-A" ??? someone try to replace that ??

Thank you

Try to compare i/o ports of temperature sensors by schematics diagrams.
If differences will be found - it impossible to change with that one.
Only with absolute coincidence MCUs can be used as donors.

Tables of I/O ports of sensors are programmed at memory regions in MCU, and can not be reprogrammed by usual methods.

In this case You can use this MCU only for diagnostics use.

Already understood.

I will buy a same donor board to remove the SMC. Thank you one more time
