68 / 131 page  Electrical characteristics STM32L151x6/8/B, STM32L152x6/8/B 68/131 DocID17659 Rev 9 All timings are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 13. 6.3.6 External clock source characteristics High-speed external user clock generated from an external source In bypass mode the HSE oscillator is switched off and the input pin is a standard GPIO. The external clock signal has to respect the I/O characteristics in Section 6.3.13. However, the recommended clock input waveform is shown in Figure 15: High-speed external clock source AC timing diagram. Table 25. Low-power mode wakeup timings Symbol Parameter Conditions Typ Max(1) 1. Based on characterization, not tested in production, unless otherwise specified Unit tWUSLEEP Wakeup from Sleep mode fHCLK = 32 MHz 0.36 - µs tWUSLEEP_LP Wakeup from Low power sleep mode fHCLK = 262 kHz fHCLK = 262 kHz Flash enabled 32 - fHCLK = 262 kHz Flash switched OFF 34 - tWUSTOP Wakeup from Stop mode, regulator in Run mode fHCLK = fMSI = 4.2 MHz 8.2 - Wakeup from Stop mode, regulator in low power mode fHCLK = fMSI = 4.2 MHz Voltage Range 1 and 2 8.2 9.3 fHCLK = fMSI = 4.2 MHz Voltage Range 3 7.8 11.2 fHCLK = fMSI = 2.1 MHz 10 12 fHCLK = fMSI = 1.05 MHz 15.5 20 fHCLK = fMSI = 524 kHz 29 35 fHCLK = fMSI = 262 kHz 53 63 fHCLK = fMSI = 131 kHz 105 118 fHCLK = MSI = 65 kHz 210 237 tWUSTDBY Wakeup from Standby mode FWU bit = 1 fHCLK = MSI = 2.1 MHz 50 103 Wakeup from Standby mode FWU bit = 0 fHCLK = MSI = 2.1 MHz 2.5 3.2 ms |
