After testing my microcontroller in my circuit, everything seems to be OK so far, BUT as soon as I applied 12V to the VPP pin of my AT89C2051 uC, the temperature slowly rises in the microcontroller, but it never reaches the burning point. When I removed the 12V from the VPP and connected it to ground, the uC cools down and returns to normal temperature.
Is this normal operation?
