*) Type means: A = 100% tested, B = 100% correlation tested, C = Characterized on samples, D = Design parameter

Notes:

1. VDDIO is the supply voltage for the following GPIO-pins: P1, P2, P8, P12, P14, P16, P17, P18, P19, P20, P21, P23, P24,

P25, P26, P27 and P29

2. Values defined for operating the USB interface. Otherwise VDD_USB may be connected to 1.8V or 0V supply.

3. Supply voltage VBAT18 for backup domain is generated internally by the LDOBAT.
