Table 14. Voltage characteristics (1)
- VIN maximum must always be respected. Refer to Table 15: Current characteristics for the maximum allowed injected current values.
- This formula has to be applied only on the power supplies related to the IO structure described in the pin definition table.
- To sustain a voltage higher than 4 V the internal pull-up/pull-down resistors must be disabled.
- Include VREF- pin.
- This current consumption must be correctly distributed over all I/Os and control pins. The total output current must not be sunk/sourced between two consecutive power supply pins referring to high pin count LQFP packages.
- Positive injection (when V IN > V DD ) is not possible on these I/Os and does not occur for input voltages lower than the specified maximum value.
- A negative injection is induced by VIN < VSS. IINJ(PIN) must never be exceeded. Refer also to Table 14: Voltage characteristics for the minimum allowed input voltage values.
- When several inputs are submitted to a current injection, the maximum ∑ |I INJ(PIN) | is the absolute sum of the negative injected currents (instantaneous values).
