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

2. For temperature range 3.

3. Flash is configured in IDDQ mode in Wait mode by setting the EPM or WAITM bit in the Flash_CR1 register.

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

(IDD HSE) must be added. Refer to Table 30.

5. Tested in production.

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

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