43 / 93 page  DS9773 Rev 4 43/93 STM32F030x4/x6/x8/xC Electrical characteristics 75 6.2 Absolute maximum ratings Stresses above the absolute maximum ratings listed in Table 18: Voltage characteristics, Table 19: Current characteristics and Table 20: 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 18. Voltage characteristics(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. Symbol Ratings Min Max Unit VDD–VSS External main supply voltage -0.3 4.0 V VDDA–VSS External analog supply voltage -0.3 4.0 V VDD–VDDA Allowed voltage difference for VDD > VDDA -0.4 V VIN(2) 2. VIN maximum must always be respected. Refer to Table 19: Current characteristics for the maximum allowed injected current values. Input voltage on FT and FTf pins VSS −0.3 VDDIOx + 4.0 (3) 3. VDDIOx is internally connected with VDD pin. V Input voltage on TTa pins VSS −0.3 4.0 V BOOT0 0 VDDIOx + 4.0 (3) V Input voltage on any other pin VSS −0.3 4.0 V | ΔVDDx| Variations between different VDD power pins - 50 mV |VSSx −VSS| Variations between all the different ground pins -50 mV VESD(HBM) Electrostatic discharge voltage (human body model) see Section 6.3.12: Electrical sensitivity characteristics - |
