Specifications

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.

Voltage characteristics

Symbol	Ratings	Min	Max	Unit
VDD_x - VSS_X (1)	Including VDDA_ADC and VDDA_PLL	-0.3	6.5	V
V18 - VSS18	Digital 1.8 V Supply voltage on all V18 power pins (when 1.8 V is provided externally)	-0.3	2.0
VIN	Input voltage on any pin (2)	VSS-0.3 to VDD_IO+0.3	VSS-0.3 to VDD_IO+0.3
|VDDx|	Variations between different 3.3 V or 5.0 V power pins		50	mV
|V18x|	Variations between different 1.8 V power pins(3)		25
|VSSX - VSS|	Variations between all the different ground pins		50
VESD(HBM)	Electro-static discharge voltage (Human Body Model)	see : Absolute Maximum Ratings (Electrical Sensitivity) on page 52	see : Absolute Maximum Ratings (Electrical Sensitivity) on page 52
VESD(MM)	Electro-static discharge voltage (Machine Model)

1. All 3.3 V or 5.0 V power (V_{DD_IO}, V_{DDA_ADC}, V_{DDA_PLL}) and ground (V_{SS_IO}, V_{SSA_ADC}, V_{DDA_ADC}) pins must always be connected to the external 3.3V or 5.0V supply. When powered by 3.3V, I/Os are not 5V tolerant.
2. I_INJ(PIN) must never be exceeded. This is implicitly insured if V_IN maximum is respected. If V_IN maximum cannot be respected, the injection current must be limited externally to the I_INJ(PIN) value. A positive injection is induced by V_IN>V_DD while a negative injection is induced by V_IN<V_SS. For true open-drain pads,there is no positive injection current, and the corresponding V_IN maximum must always be respected 3. Only when using external 1.8 V power supply. All the power (V₁₈, V_18REG, V_18BKP) and ground (V_SS18,V_SSBKP) pins must always be connected to the external 1.8 V supply.
3. Only when using external 1.8 V power supply. All the power (V₁₈, V_18REG, V_18BKP) and ground (V_SS18,V_SSBKP) pins must always be connected to the external 1.8 V supply.

Current characteristics

Symbol	Ratings	Maximum value	Unit
IVDD_IO (1)	Total current into VDD_IO power lines (source) (2)	150	mA
IVSS_IO (1)	Total current out of VSS ground lines (sink)(2)	150
IIO	Output current sunk by any I/O and control pin	25
	Output current source by any I/Os and control pin	-25
IINJ(PIN)3) & 4)	Injected current on NRSTIN pin	± 5
	Injected current on XT1 and XT2 pins	± 5
	Injected current on any other pin (5)	± 5
IINJ(PIN) 2)	Total injected current (sum of all I/O and control pins) 5)	± 25

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.
2. All 3.3 V or 5.0 V power (V_{DD_IO}, V_{DDA_ADC}, V_{DDA_PLL}) and ground (V_{SS_IO}, V_{SSA_ADC}, V_{DDA_ADC}) pins must always be connected to the external 3.3V or 5.0V supply.
3. I_INJ(PIN) must never be exceeded. This is implicitly insured if V_IN maximum is respected. If V_IN maximum cannot be respected, the injection current must be limited externally to the I_INJ(PIN) value. A positive injection is induced by V_IN>V_DD while a negative injection is induced by V_IN<V_SS.
4. Negative injection disturbs the analog performance of the device. See note in Section 5.3.12: 10-bit ADC
characteristics on page 72.
5. When several inputs are submitted to a current injection, the maximum I_INJ(PIN) is the absolute sum of the
positive and negative injected currents (instantaneous values). These results are based on characterization with I_INJ(PIN) maximum current injection on four I/O port pins of the device.
