<ul data-eligibleForWebStory="false"><li>An exploit named PIC Burnout allows for dumping the One Time Programming (OTP) memory in certain Microchip PIC MCUs with code protection enabled.</li><li>This exploit damages the memory contents, meaning only one attempt can likely be made to dump the OTP data before the memory is 'burned out'.</li><li>The exploit involves using excessively high programming voltage and duration to circumvent the scrambled OTP data, and requires multiple checks to ensure successful data readouts.</li><li>While this method can affect the entire flash bit column, it is harsh on memory cells and may take hours to obtain a good dump. Knowledge of the scrambling method used is also necessary.</li></ul>
