114 / 220 page  Electrical characteristics STM32F469xx 114/220 DS11189 Rev 7 5.3.8 Wakeup time from low-power modes The wakeup times given in Table 34 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 34. Low-power mode wakeup timings Symbol Parameter Conditions Typ(1) Max(1) Unit tWUSLEEP(2) Wakeup from Sleep - 5 6 CPU clock cycles tWUSTOP(2) Wakeup from Stop mode with MR/LP regulator in normal mode Main regulator is ON 12.9 15.0 µs Main regulator is ON and Flash memory in Deep power down mode 105 120 Low power regulator is ON 22 28 Low power regulator is ON and Flash memory in Deep power down mode 114 130 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) 107 114 Low power regulator in under-drive mode (Flash memory in Deep power-down mode) 115 121 tWUSTDBY (2)(3) Wakeup from Standby mode - 318 371 1. Based on test during characterization. 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. |
