16.2 Absolute Maximum Ratings
Stresses above those listed as “absolute maximum ratings” may cause permanent damage to the device.
This is a stress rating only. Functional operation of the device under these conditions is not implied.
Exposure to maximum rating conditions for extended periods may affect device reliability.

Notes:
1. Connecting I/O Pins directly to VDD or VSS could damage the device if the unintentional internal reset
is generated or an unexpected change of I/O configuration occurs (for example, due to the corrupted
program counter). In order to guarantee safe operation, this connection has to be performed via a pull-
up or pull-down resistor (typical: 10K Ω for I/Os). Unused I/O pins must be tied in the same manner to
VDD or VSS according to their reset configuration.
2. When the current limitation is not possible, the VIN absolute maximum rating must be respected, other-
wise refer to IINJ(PIN) specification. A positive injection is induced by VIN>VDD while a negative injec-
tion is induced by VIN<VSS to IINJ(PIN) specification. A positive injection is VIN>VDD while a negative
injection is induced by VIN<VSS. Data by design.
3. All power (VDD) and ground (VSS) lines must always be connected to the external supply.
4. When several inputs are submitted to a current injection, the maximum
ΣIINJ(PIN) is the absolute sum of
the positive and negative injected currents (instantaneous values). Data by design.
