Pin output voltage

The input voltage measurement on a pin is described in Figure 6.

Absolute maximum ratings

Stresses above those listed as 'absolute maximum ratings' may cause permanent damage

to the device. This is a stress rating only and functional operation of the device under these

conditions is not implied. Exposure to maximum rating conditions for extended periods may

affect the device reliability.

VDDX - VSSX Supply voltage(1)

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

power supply.

VIN

Input voltage on any other pin(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.

VDD - VDDA Variation between different power pins

VSS - VSSA Variation between all the different ground pins(3)

3. VSS and VSSA signals must be interconnected together with a short wire loop.
