Recently I lost three boards (Controller heating once supply is connected, No VDDA, VDDX and VDDC supply) and dont know the reason. There is no problem from the power supply side, I have given 12V supply to the board with Aplab Bench Supply. Is there any one having same issue or anybody cna suggest the possible reason for the chip failure.</P></BODY></HTML> Thu, 17 Dec 2015 06:04:10 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/S12ZVC-Power-supply-Issue/m-p/490735#M12125 kiranbhat 2015-12-17T06:04:10Z Re: S12ZVC Power supply Issue https://community.nxp.com/t5/S12-MagniV-Microcontrollers/S12ZVC-Power-supply-Issue/m-p/490736#M12126 <HTML><HEAD></HEAD><BODY><P><SPAN style="font-size: 10.0pt; font-family: 'Arial','sans-serif';">Hi kiran,</SPAN></P><P><SPAN style="font-size: 10.0pt; font-family: 'Arial','sans-serif';">When controller heating once supply is connected, it typically means that there is some short on board or MCU is damaged.
