Требование диода в цепи батареи для STM32F0 - это что за хня? Что, обычная литиевая таблетка взорвется? During the startup phase, if VDD is established in less than tRSTTEMPO
(Refer to the datasheet for the value of tRSTTEMPO) and VDD > VBAT +
0.6 V, a current may be injected into VBAT through an internal diode
connected between VDD and the power switch (VBAT).
If the power supply/battery connected to the VBAT pin cannot support
this current injection, it is strongly recommended to connect an
external low-drop diode between this power supply and the VBAT pin.
