IVDD_IO

(1)

The user can use GPIOs to source or sink high current (up to 20 mA for O8 type High Sink I/Os). In this

case, the user must ensure that these absolute max. values are not exceeded (taking into account the

RUN power consumption) and must follow the rules described in Section 5.3.8: I/O port pin characteristics

on page 54.

Total current into VDD_IO power lines (source)

(2)

All 3.3 V or 5.0 V power (VDD_IO, VDDA_ADC, VDDA_PLL) and ground (VSS_IO, VSSA_ADC, VDDA_ADC) pins

must always be connected to the external 3.3V or 5.0V supply.

IINJ(PIN)

(3) & (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.

Negative injection disturbs the analog performance of the device. See note in Section 5.3.12: 10-bit ADC

characteristics on page 72.

Injected current on NRSTIN pin

Injected current on XT1 and XT2 pins

± 5

Injected current on any other pin (5)

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.
