I need a replacement for a A2C00536100 microcontroller. Looks like this is obsolete.
I can not found the pinout or a replacement chip.
this comes in a truck instrument cluster and drives the step motor gauges and digital odometer.

Hello softech.cr,
Welcome to the DigiKey TechForum.
We do not have any documentation on this microcontroller, and I did not find a datasheet on-line.
Chances are the part number is a proprietary part for the OEM of the vehicle.
If you are able to find a replacement, you will still have to figure out how to program the microcontroller, as it will not know what to do “Out of the Box”.
