Gave 15V as ADC input by mistake

Hi

After giving 15V to PC3 (ADC3 channel 13), I'm unable to reprogram the flash. It says ''Flash loader program reported an error''. If there is a remedy, how can I go around this?

Have I permanently damaged the MCU?

Thanks in advance

Terence

You could try the usual steps, such as mass erase in bootloader mode.

Perhaps the damage is restricted to GPIOC and/or the ADC.

But if you had a pin connected to a low-resistance 15V source, chances are high the part is blown.
