1. Data based on characterization results, not tested in production.
2. All power (VDD, VDDIO, VDDA) and ground (VSS, VSSIO, VSSA) pins must always be connected to the
external supply.
3. I/O pins used simultaneously for high current source/sink must be uniformly spaced around the package
between the VDDIO/VSSIO pins.
4. 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. For true open-drain pads,
there is no positive injection current, and the corresponding VIN maximum must always be respected
5. Negative injection disturbs the analog performance of the device. See note in Section 10.3.10: 10-bit ADC
characteristics on page 83.
6. 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). These results are based on
characterization with ΣIINJ(PIN) maximum current injection on four I/O port pins of the device.
