Electrical characteristics

4.3.1

Power domains and power up/down sequencing

The following table shows the constraints and relationships for the different power domains.

Supply1 (on rows) can exceed Supply2 (on columns), only if the cell at the given row and

column is reporting ‘ok’. This limitation is valid during power-up and power-down phases, as

well as during normal device operation.

1. The ranges in this table are design targets and actual data may vary in the given range.

2. Core voltage as measured on device pin to guarantee published silicon performance.

3. Core voltage can exceed 1.26 V with the limitations provided in Section 4.2: Absolute maximum ratings, provided that

HVD134_C monitor reset is disabled.

4. 1.260 V - 1.290 V range allowed periodically for supply with sinusoidal shape and average supply value below or equal to

1.236 V at the given temperature profile.

5. Full device lifetime. I/O and analog input specifications are only valid if the injection current on adjacent pins is within these

limits. See Section 4.2: Absolute maximum ratings for maximum input current for reliability requirements.

6. The I/O pins on the device are clamped to the I/O supply rails for ESD protection. When the voltage of the input pins is

above the supply rail, current will be injected through the clamp diode to the supply rails. For external RC network

calculation, assume typical 0.3 V drop across the active diode. The diode voltage drop varies with temperature.

7. The limits for the sum of all normal and injected currents on all pads within the same supply segment can be found in

Section 4.8.3: I/O pad current specifications.

Positive and negative Dynamic current injection pulses are allowed up to this limit. I/O and ADC specifications are not

granted. See the dedicated chapters for the different specification limits. See the Absolute Maximum Ratings table for

maximum input current for reliability requirements. Refer to the following pulses definitions: Pulse1 (ISO 7637-2:2011),

Pulse 2a(ISO 7637-2:2011 5.6.2), Pulse 3a (ISO 7637-2:2011 5.6.3), Pulse 3b (ISO 7637-2:2011 5.6.3).
