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.

All 5 V power (VDD, VDDA) and ground (VSS, VSSA) pins must always be connected to the external 5 V

supply

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.

Negative injection disturbs the analog performance of the device. See note in Section 4.3.6: 10-bit ADC

characteristics on page 43.

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).
