Hi ST team,
Looking over the device datasheet, I had expected to see maximum current consumption at least under TX and RX conditions so I can design power management appropriately. When this information is missing, I typically look for a maximum ICC specification as the next best point of reference but that's missing as well. Has there been any testing or is there a maximum ICC by device design to which I can design my power management solution?
HSE and LSE signals; I found a post at Migrating from the SPWF01Sx to the SPWF04Sx that says to ignore these pins and float. The X-NUCLEO board ties these to a crystal and RTC respectively. What purpose do these serve? Also, if these are inputs, shouldn't these be tied to a logic level to prevent oscillating inputs?
