44 / 101 page ![]() Electrical characteristics STM32F101x8, STM32F101xB 44/101 DocID13586 Rev 17 5.3.6 External clock source characteristics High-speed external user clock generated from an external source The characteristics given in Table 19 result from tests performed using an high-speed external clock source, and under the ambient temperature and supply voltage conditions summarized in Table 8. Table 18. Peripheral current consumption Peripheral Typical consumption at 25 °C(1) 1. fHCLK = 36 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, default prescaler value for each peripheral. Unit AHB (up to 36 MHz) DMA1 16.53 μA/MHz BusMatrix(2) 2. The BusMatrix is automatically active when at least one master is ON. 8.33 APB1 (up to 18 MHz) APB1-Bridge 10.28 TIM2 32.50 TIM3 31.39 TIM4 31.94 SPI2 4.17 USART2 12.22 USART3 12.22 I2C1 10.00 I2C2 10.00 WWDG 2.50 PWR 1.67 BKP 2.50 IWDG 11.67 APB2 (up to 36 MHz) APB2-Bridge 3.75 GPIO A 6.67 GPIO B 6.53 GPIO C 6.53 GPIO D 6.53 GPIO E 6.39 ADC1(3) 3. Specific conditions for ADC: fHCLK = 28 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, fADCCLK = fAPB2/2 . When ADON bit in the ADC_CR2 register is set to 1, the consumption added is equal to 0.65 mA. When the ADC is enabled, a current consumption is added equal to 0.05 mA. 17.50 SPI1 4.72 USART1 11.94 |
