1. Parametric figures can be out of specification when voltage drops below 4.5 V, however, guaranteeing the full functionality.

In particular, ADC electrical characteristics and I/Os DC electrical specification may not be guaranteed.

2. The difference between each couple of voltage supplies must be less than 100 mV, |VDD_HV_IOy – VDD_HV_IOx | < 100 mV.

3. To be connected to emitter of external NPN. Low voltage supplies are not under user control—these are produced by an

on-chip voltage regulator—but for the device to function properly the low voltage grounds (VSS_LV_xxx) must be shorted to

high voltage grounds (VSS_HV_xxx) and the low voltage supply pins (VDD_LV_xxx) must be connected to the external ballast

emitter.

4. The low voltage supplies (VDD_LV_xxx) are not all independent. 

VDD_LV_COR1 and VDD_LV_COR2 are shorted internally via double bonding connections with lines that provide the low

voltage supply to the data flash memory module. Similarly, VSS_LV_COR1 and VSS_LV_COR2 are internally shorted.

VDD_LV_REGCOR and VDD_LV_REGCORx are physically shorted internally, as are VSS_LV_REGCOR and VSS_LV_CORx.
