12.2 ABSOLUTE MAXIMUM RATINGS
Stresses above those listed as “absolute maxi-
mum ratings” may cause permanent damage to
the device. This is a stress rating only and func-

Notes:
1. Directly connecting the RESET and I/O pins to V
is generated or 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: 4.7kΩ for
RESET, 10kΩ for I/Os). For the same reason, unused I/O pins must not be directly tied to V
2. I
respected, the injection current must be limited externally to the I
while a negative injection is induced by V
3. All power (V
4. Negative injection disturbs the analog performance of the device. See note in
page
For best reliability, it is recommended to avoid negative injection of more than 1.6mA
5. When several inputs are submitted to a current injection, the maximum ΣI
and negative injected currents (instantaneous values). These results are based on characterisation with ΣI
mum current injection on four I/O port pins of the device.
