Doc ID 16912 Rev 5 839/936
Voltage Regulator Status register (VREG_STATUS)
34.2 Power supply strategy
The SPC560P40/34 provides three dedicated supply domains at the package level:
● HV—High voltage external power supply for I/Os, voltage regulator module, and most
analog modules
This must be provided externally through V
DD_HV
/V
SS_HV
power pins. Voltage values
should be aligned with V
DD
/V
SS
. Refer to the device datasheet for details.
● ADC—High voltage external power supply for ADC module
This must be provided externally through V
DD_HV_ADx
/V
SS_HV_ADx
power pins. Voltage
values should be aligned with V
DD_HV_ADx
/V
SS_HV_ADx
. Refer to the device datasheet
for details.
● LV—Low voltage internal power supply for core, PLL, and flash digital logic
This is provided to the core, PLL and flash. Five V
DD_LV
/V
SS_LV
pins pairs are provided
to connect the low voltage power supply. Refer to the device datasheet for details.
