Sorry for the bad news. Static electricity is very sneaky. Over the years I’ve damaged several microcontrollers by what I can only assume is static electricity. These IC’s can only handle at most 13 volts on a pin, but a static discharge isn’t even detectable by our senses until it is over 1000 volts…so they are really easy to damage without knowing it. And most of the time it doesn’t completely kill the chip, it only damages part of its functionality.
Unfortunately, these flashed uCs are only available from us directly, not any of our distributors.
But yes, please contact me via email and we’ll discuss this.
