Pin input voltage

The input voltage measurement on a pin of the device is described in Figure 10.

Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 20: Voltage characteristics,

Table 21: Current characteristics and Table 22: 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 the device’s reliability. The device’s mission profile (application

conditions) is compliant with the JEDEC JESD47 qualification standard, extended mission

profiles are available on demand.

VDDx - VSS Supply voltage (including VDDA and VDDIO)(1)

1. All power (VDD, VDDIO, VDDA) and ground (VSS, VSSIO, VSSA) pins must always be connected to the

external power supply

Input voltage on true open drain pins (PE1, PE2)(2)

2. IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum

cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive

injection is induced by VIN > VDD while a negative injection is induced by VIN < VSS. For true open-drain

pads, there is no positive injection current, and the corresponding VIN maximum must always be respected
