- Digital ground for Ballast I/O B7
V
18
-
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 10F (Tantalum, low
series resistance) + 33nF (ceramic) shall be connected between
these pins and V
SS18
to guarantee on-chip voltage stability.
B3, F5
V
SS18
- Digital ground for core circuitry B2, E5
V
18BKP
-
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 1F shall be connected between this pin and
V
SSBKP
to guarantee on-chip voltage stability.
