Something is puzzling me. In the reference manual for the STML0x1 devices (Figure 11 and in other places) it states that, for Vcore Range 1, Vcore is regulated to 1.8V. It states that this is true for Vdd of 1.71V to 3.6V.

Can someone please explain how 1.8V is acheived from 1.71V please?


Is Vcore boosted somehow or does it fall to 1.71V?

If it does fall to 1.71V, I assume it is OK to run at 32MHz?


Thank you!
