1. All peripherals OFF, VDD from 1.65 V to 3.6 V, HSI internal RC osc., fCPU=fSYSCLK

2. For devices with suffix 6

3. For devices with suffix 7

4. For devices with suffix 3

5. CPU executing typical data processing

6. The run from RAM consumption can be approximated with the linear formula:

IDD(run_from_RAM) = Freq. * 95 µA/MHz + 250 µA

7. Tested in production.

8. Oscillator bypassed (HSEBYP = 1 in CLK_ECKCR). When configured for external crystal, the HSE consumption

(IDD HSE) must be added. Refer to Table 31.

9. The run from Flash consumption can be approximated with the linear formula:

IDD(run_from_Flash) = Freq. * 200 µA/MHz + 330 µA

10. Oscillator bypassed (LSEBYP = 1 in CLK_ECKCR). When configured for external crystal, the LSE consumption

(IDD LSE) must be added. Refer to Table 32
