Power supply pins
Symbol
VDD18_MVR
I/O
Functions
TFBGA169
Pwr
Digital supply voltage for main voltage regulator (1.8 V)
D3, G8
Digital supply voltage for core circuitry (1.2 V). When using the
MVR, this pin shall not be driven by an external voltage supply, but
a capacitance shall be connected between these pins and GND to
guarantee on-chip voltage stability.
VDD12_MVR
VDD_LPVR
Pwr
Pwr
Pwr
J7, D4, J9
Digital supply voltage for low power voltage regulator (1.62 V -
3.6 V)
J8
Digital supply voltage for backup logic (1.2 V). When using the
LPVR, this pin shall not be driven by an external voltage supply,
but a capacitance shall be connected between these pins and
GND to guarantee on-chip voltage stability.
