58 / 117 page  Electrical characteristics STM32F042x4 STM32F042x6 58/117 DocID025832 Rev 5 On-chip peripheral current consumption The current consumption of the on-chip peripherals is given in Table 32. The MCU is placed under the following conditions: • All I/O pins are in analog mode • 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 supply voltage conditions summarized in Table 18: Voltage characteristics Table 32. Peripheral current consumption Peripheral Typical consumption at 25 °C Unit AHB BusMatrix(1) 2.2 µA/MHz CRC 1.9 DMA 5.1 Flash memory interface 15.0 GPIOA 8.2 GPIOB 7.7 GPIOC 2.1 GPIOF 1.8 SRAM 1.1 TSC 4.9 All AHB peripherals 49.8 |
