1. Device will be functional down (and electrical specifications as per various datasheet parameters will be guaranteed) to the
point where the LVD_IO_A_LO resets the device. When voltage drops below VLVD_IO_A_LO, device is reset.
2. VDD_HV_A, VDD_HV_B and VDD_HV_C are all independent supplies and can each be set to 3.3V or 5V. For example, if
VDD_HV_A = 5V, then VDD_HV_B and VDD_HV_C can both be 3.3V. However, care must be taken over ADC inputs that
operate across the IO segments (Subject to Note 1).
3. VDD_HV_FLA must be connected to VDD_HV_A when VDD_HV_A = 3.3V
4. PA3, PA7, PA10, PA11 and PE12 ADC_1 channels are coming from VDD_HV_B domain hence VDD_HV_ADC1 should
be within ±100 mV of VDD_HV_B when these channels are used for ADC_1.
5. Only applicable when supplying from external source.
6. VIN1_CMP_REF ≤ VDD_HV_A
7. This supply is shorted VDD_HV_A on lower packages.
8. Tj=150°C. Assumes Ta=125°C
• Assumes maximum θJA. SeeThermal attributes
NOTE
• If VDD_HV_A is in 5V range, it is necessary to use
internal Flash supply 3.3V regulator. VDD_HV_FLA
should not be supplied externally and should only have
decoupling capacitor.
