I've already become familiar with the NUCLEO-C071 by creating some additional hardware (display, encoder, etc.). Now, I want to design a board using the smaller 32-pin version. However, in this smaller version, I find some differences that I don't know how to address (I have read the datasheet thoroughly multiple times but cannot find any answers):
1) In the 64-pin version, pin 6 is the VBAT to connect a battery or a supercapacitor to maintain the RTC operation in case of power loss. Where has it gone in the 32-pin version?
2) In the 64-pin version, both the quartz for the CPU and for the RTC can be mounted. Can you confirm that in the 32-pin version, the CPU only works without quartz? Even for managing USB?
Thank you to anyone who can help me.
Luca.
