Pin input voltage

The input voltage measurement on a pin of the device is described in Figure 51.

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.

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 VDD or VSS

according to their reset configuration.

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.
