Digital ground for ballast I/O
Digital supply voltage for core circuitry (1.8 Volt):
when using the internal voltage regulator, this pin
shall not be driven by an external voltage supply, but
a capacitance of at least 10μF (tantalum, low series
resistance) + 33nF (ceramic) shall be connected
between these pins and V
voltage stability.
Digital Ground for core circuitry
Digital supply voltage for backup block (RTC,
oscillator, Wake-up controller - 1.8 Volt): when using
the internal voltage regulator, this pin shall not be
driven by an external voltage supply, but a
capacitance of at least 1μF shall be connected
between this pin and V
voltage stability.
