49 / 116 page ![]() DS5319 Rev 18 49/116 STM32F103x8, STM32F103xB Electrical characteristics 115 On-chip peripheral current consumption The current consumption of the on-chip peripherals is given in Table 19. The MCU is put under the following conditions: all I/O pins are in input mode with a static value at VDD or VSS (no load) all peripherals are disabled unless otherwise mentioned the given value is calculated by measuring the current consumption – with all peripherals clocked off – with only one peripheral clocked on ambient operating temperature and VDD supply voltage conditions summarized in Table 6 Table 19.
