Voltage regulator electrical characteristics

The device implements an internal voltage regulator to generate the low voltage core supply VDD_LV from

the high voltage ballast supply VDD_BV. The regulator itself is supplied by the common I/O supply VDD.

The following supplies are involved:

•

HV: High voltage external power supply for voltage regulator module. This must be provided

externally through VDD power pin.

•

BV: High voltage external power supply for internal ballast module. This must be provided

externally through VDD_BV power pin. Voltage values should be aligned with VDD.

•

LV: Low voltage internal power supply for core, FMPLL and Flash digital logic. This is generated

by the internal voltage regulator but provided outside to connect stability capacitor. It is further

split into four main domains to ensure noise isolation between critical LV modules within the

device:

— LV_COR: Low voltage supply for the core. It is also used to provide supply for FMPLL

through double bonding.

— LV_CFLA: Low voltage supply for code flash module. It is supplied with dedicated ballast and

shorted to LV_COR through double bonding.

— LV_DFLA: Low voltage supply for data flash module. It is supplied with dedicated ballast and

shorted to LV_COR through double bonding.

— LV_PLL: Low voltage supply for FMPLL. It is shorted to LV_COR through double bonding.
