83 / 175 page  DocID17050 Rev 9 83/175 STM32F21xxx Electrical characteristics 174 On-chip peripheral current consumption The current consumption of the on-chip peripherals is given in Table 25. The MCU is placed under the following conditions: • At startup, all I/O pins are configured as analog inputs by firmware. • All peripherals are disabled unless otherwise mentioned • The given value is calculated by measuring the current consumption – with all peripherals clocked off – with one peripheral clocked on (with only the clock applied) • The code is running from Flash memory and the Flash memory access time is equal to 3 wait states at 120 MHz • Prefetch and Cache ON • When the peripherals are enabled, HCLK = 120MHz, fPCLK1 = fHCLK/4, and fPCLK2 =fHCLK/2 • The typical values are obtained for VDD = 3.3 V and TA= 25 °C, unless otherwise specified. |
