I'm having an important issue with some microcontrollers LPC11U67 48 pin. If I set internal frequency at 48Mhz some of them (more or less 5/10%) stop if I put them at a temperature of 40°C.
If, on the same micros, I set a 36Mhz clock frequency, the problem disappears and they don't stop.
The same problem is described in this topic of 3 years ago.
Has anyone the same problem?
I'm asking it because I do need to go at 48Mhz (36MHz is not enough).
