42 / 87 page ![]() Electrical characteristics STM32F101x4, STM32F101x6 42/87 DocID15058 Rev 6 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 Unit AHB (up to 36 MHz) DMA1 15.97 μA/MHz CRC 1.67 BusMatrix(1) 1. The BusMatrix is automatically active when at least one master is ON. (CPU, DMA1) . 8.33 APB1 (up to 18 MHz) APB1-Bridge 7.22 TIM2 33.33 TIM3 33.61 USART2 12.78 I2C1 10.83 WWDG 3.33 PWR 1.94 BKP 2.78 IWDG 1.39 APB2 (up to 36 MHz) APB2-Bridge 3.33 GPIO A 7.50 GPIO B 6.81 GPIO C 7.22 GPIO D 6.94 SPI1 4.86 USART1 12.78 ADC1(2) 2. Specific conditions for measuring ADC current consumption: fHCLK = 28 MHz, fAPB1 = fHCLK, fAPB2 = fHCLK, fADCCLK = fAPB2 / 2. When ADON bit in the ADC_CR2 register is set to 1, a current consumption of analog part equal to 0.7 mA must be added. 15.54 |
