Root Cause

Supply voltage dropped below brownout threshold causing reset.

generic

Workarounds

  1. 88% success Check power supply decoupling capacitors (100nF + 10uF near VDD)
  2. 85% success Add bulk capacitance for transient loads

Dead Ends

Common approaches that don't work:

  1. Disable brownout detection 85% fail

    Runs at unsafe voltage, data corruption

  2. Lower brownout threshold 80% fail

    Chip operates out of spec
