Pin input voltage

The input voltage measurement on a pin of the device is described in Figure 38.

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 device reliability.

1. Directly connecting the I/O pins to VDD or VSS could damage the device if an unexpected

change of the I/O configuration occurs (for example, due to a corrupted program counter).

To guarantee safe operation, this connection has to be done through a pull-up or pull-down

resistor (typical: 10 k

Ω for I/Os). Unused I/O pins must be tied in the same way to V

DD or

VSS according to their reset configuration.

VIN

Input voltage on any pin(1)

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.
