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.
All 5 V power (VDD, VDDA) and ground (VSS, VSSA) pins must always be connected to the external 5 V
supply
2.
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.
3.
Negative injection disturbs the analog performance of the device. See note in Section 4.3.6: 10-bit ADC
4.
When several inputs are submitted to a current injection, the maximum
ΣI
INJ(PIN) is the absolute sum of the
positive and negative injected currents (instantaneous values). These results are based on
characterization with
ΣI
INJ(PIN) maximum current injection on four I/O port pins of the device.
5.) In 144-pin devices, only +10 mA on P0.3, P1.13, P3.6 and P4.13 pins (negative injection not allowed).
