115 / 231 page ![]() DocID024030 Rev 6 115/231 STM32F427xx STM32F429xx Electrical characteristics 192 6.3.8 Wakeup time from low-power modes The wakeup times given in Table 36 are measured starting from the wakeup event trigger up to the first instruction executed by the CPU: • For Stop or Sleep modes: the wakeup event is WFE. • WKUP (PA0) pin is used to wakeup from Standby, Stop and Sleep modes. All timings are derived from tests performed under ambient temperature and VDD=3.3 V. Table 36. Low-power mode wakeup timings Symbol Parameter Conditions Typ(1) Max(1) Unit tWUSLEEP(2) Wakeup from Sleep - 6 - CPU clock cycle tWUSTOP(2) Wakeup from Stop mode with MR/LP regulator in normal mode Main regulator is ON 13.6 - µs Main regulator is ON and Flash memory in Deep power down mode 93 111 Low power regulator is ON 22 32 Low power regulator is ON and Flash memory in Deep power down mode 103 126 tWUSTOP(2) Wakeup from Stop mode with MR/LP regulator in Under-drive mode Main regulator in under-drive mode (Flash memory in Deep power-down mode) 105 128 Low power regulator in under-drive mode (Flash memory in Deep power-down mode ) 125 155 tWUSTDBY (2)(3) Wakeup from Standby mode 318 412 1. Guaranteed by characterization results. 2. The wakeup times are measured from the wakeup event to the point in which the application code reads the first 3. tWUSTDBY maximum value is given at –40 °C. |
