1. 'X' means that the pin is present.
2. 'o' means that VDD and VDDUSB are internally connected and available on a single pin.
3. 'o' means that VSSA and VREF- are internally connected and available on a single pin.
4. 'o' means that VDDA and VREF+ are internally connected and available on a single pin.
5. '-' means that the pin is absent.
Caution: Packages with and without SMPS are not compatible, in almost all power supply pins of Table 2.
Example: VDDIO2 is the pin number 130 on SMPS package. Pin 130 on the package without SMPS is mapped to a VSS pin. It means that the system
is short‑circuited when a legacy package is mounted on an SMPS socket.
