44 / 110 page  Electrical characteristics STM32L081xx 44/110 DocID027513 Rev 4 6.2 Absolute maximum ratings Stresses above the absolute maximum ratings listed in Table 17: Voltage characteristics, Table 18: Current characteristics, and Table 19: Thermal characteristics may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. Table 17. Voltage characteristics Symbol Definition Min Max Unit VDD–VSS External main supply voltage (including VDDA, VDDIO2 VDD)(1) 1. All main power (VDD,, VDDA) and ground (VSS, VSSA) pins must always be connected to the external power supply, in the permitted range. –0.3 4.0 V VIN(2) 2. VIN maximum must always be respected. Refer to Table 18 for maximum allowed injected current values. Input voltage on FT and FTf pins VSS 0.3 VDD+4.0 Input voltage on TC pins VSS 0.3 4.0 Input voltage on BOOT0 VSS VDD 4.0 Input voltage on any other pin VSS 0.3 4.0 | VDD| Variations between different VDDx power pins - 50 mV |VDDA-VDDx| Variations between any VDDx and VDDA power pins(3) 3. It is recommended to power VDD and VDDA from the same source. A maximum difference of 300 mV between VDD and VDDA can be tolerated during power-up and device operation. VDDIO2 is independent from VDD and VDDA: its value does not need to respect this rule. - 300 | VSS| Variations between all different ground pins - 50 VESD(HBM) Electrostatic discharge voltage (human body model) see Section 6.3.11 |
