Functions
TFBGA169
VDD18_MVR
Pwr
Digital supply voltage for main voltage regulator (1.8 V)
D3, G8
VDD12_MVR
Pwr
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.
J7, D4, J9
VDD_LPVR
Pwr
Digital supply voltage for low power voltage regulator (1.62 V -
3.6 V)
J8
VDD12_LPVR
Pwr
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.
