1) Can you advise what is the lower limit for RAM voltage - i.e. what voltage causes that RAM is lost?
2) If we have SVSHE=1, device should reset at 1.75V-1.85V and all pins would be in high impedance, is it right?
Main reason for my questions is that we would protect RAM by SVS, but it doesn´t work. When we measure (oscilloscope) supply voltage, SVS works fine (the lowest voltage is about 1.78, then it resets), but some cells in RAM are damaged.
