29 / 80 page  DocID15056 Rev 5 29/80 STM32F102x8, STM32F102xB Electrical characteristics 79 Table 6. Current characteristics Symbol Ratings Max. Unit IVDD Total current into VDD/VDDA power lines (source)(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. 150 mA IVSS Total current out of VSS ground lines (sink)(1) 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) (2) 2. Negative injection disturbs the analog performance of the device. See Note: on page 66. Injected current five volt tolerant pins(3) 3. Positive injection is not possible on these I/Os. A negative injection is induced by VIN<VSS. IINJ(PIN) must never be exceeded. Refer to Table 5 for maximum allowed input voltage values. −5/+0 Injected current on any other pin(4) 4. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. IINJ(PIN) must never be exceeded. Refer to Table 5 for maximum allowed input voltage values. ± 5 ΣIINJ(PIN) Total injected current (sum of all I/O and control pins)(5) 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). ± 25 Table 7. Thermal characteristics Symbol Ratings Value Unit TSTG Storage temperature range –65 to +150 °C TJ Maximum junction temperature 150 °C |
