> I recall that the wide supply range is for the CPU, not necessarily its internal Flash programmer. Plus, there are restrictions that the maximum clock rate falls with the voltage, so you can't run at top speed with only 1.8V ... I'm sure there could be variation between PIC models, but I've worked with three or four and they don't support all features at low voltage.
That's right, for writing flash this PIC needs at least 4.5V. But we're
not writing flash, only EEPROM, which needs 2V for writing.
No need for top speed either, as it only scans one man-operated contact.
It runs at 2V up to 4MHz, while this program runs pretty damn fast at

Yes, I will cut the corners where they protrude creating cut danger.
Look what happened to car industry when cabin light dimmer required 1GHz
