Stresses above the absolute maximum ratings listed in Table 14: Voltage characteristics , Table 15: Current characteristics and Table 16: Thermal characteristics may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. Exposure to maximum rating conditions for extended periods may affect device reliability. Device mission profile (application conditions) is compliant with JEDEC JESD47 qualification standard, extended mission profiles are available on demand.

Table 14. Voltage characteristics (1)

Table 14. Voltage characteristics (1)

1. VIN maximum must always be respected. Refer to Table 15: Current characteristics for the maximum allowed injected current values.
2. This formula has to be applied only on the power supplies related to the IO structure described in the pin definition table.
3. To sustain a voltage higher than 4 V the internal pull-up/pull-down resistors must be disabled.
4. Include VREF- pin.
5. 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.
6. 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.
7. 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.
8. 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).
