48 / 96 page Electrical characteristics STM32F103x8, STM32F103xB 48/96 Doc ID 13587 Rev 12 On-chip peripheral current consumption The current consumption of the on-chip peripherals is given in Table 19. The MCU is placed 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. Peripheral current consumption(1) 1. fHCLK = 72 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, default prescaler value for each peripheral. Peripheral Typical consumption at 25 °C Unit APB1 TIM2 1.2 mA TIM3 1.2 TIM4 0.9 SPI2 0.2 USART2 0.35 USART3 0.35 I2C1 0.39 I2C2 0.39 USB 0.65 CAN 0.72 APB2 GPIO A 0.47 mA GPIO B 0.47 GPIO C 0.47 GPIO D 0.47 GPIO E 0.47 ADC1(2) 2. Specific conditions for ADC: fHCLK = 56 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, fADCCLK = fAPB2/4, ADON bit in the ADC_CR2 register is set to 1. 1.81 ADC2 1.78 TIM1 1.6 SPI1 0.43 USART1 0.85 |
