1. All voltages are referred to VSS unless otherwise specified.

2. If total power dissipation and maximum junction temperature allows. Please refer to Thermal operating characteristics

table for the maximum junction temperature, and Thermal characteristics table for the thermal characteristics, to determine

the maximum power dissipation allowed for a given package.

3. You must ensure that the junction temperature in the application must not exceed the maximum specified Tj.

4. VREFH should always be equal to or less than VDD_HV_A +0.1. Any positive differential voltage between VREFH and

VDD_HV_A i.e., VDD_HV_A < VREFH <= VDD_HV_A + 0.1V) is for RF-AC only. Appropriate decoupling capacitors should

be used to filter noise on the supplies. See application note AN5032 for reference supply design for SAR ADC.

5. Open-drain outputs must be pulled respectively to their supply rail (VDD_HV_A or VDD_HV_B).

6. When input pad voltage levels are close to VDD_HV_A (respectively to VDD_HV_B) or VSS, practically no current injection

is possible.

7. The MCU supply ramp rate parameter must be applicable to the MCU input/external supplies. The ramp rate assumes that

the S32K3xx HW design guidelines available on www.nxp.com are followed.
