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.

Supply voltage(1)

All power (VDD) and ground (VSS) lines must always be connected to the external supply.

Input voltage on any pin (2)

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: 10kW for I/Os). Unused I/O pins

must be tied in the same way to VDD or VSS according to their reset configuration.
