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 the functional operation of the device under

these conditions is not implied. Exposure to maximum rating conditions for extended

periods may affect the device reliability.

VDDX - VSSX Supply voltage(1)

1. All power VDDX (VDD, VDDA) and ground VSSX (VSS, VSSA) pins must always be connected to the external

power supply.

Input voltage on any other pin(2)

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. 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.

4. Negative injection disturbs the analog performance of the device.

5. When several inputs are submitted to a current injection, the maximum

IINJ(PIN) is the absolute sum of the

positive and negative injected currents (instantaneous values). These results are based on

characterization with

IINJ(PIN) maximum current injection on four I/O port pins of the device.
