Regulator mode transition times Symbol Parameter Conditions Typ (3 V, 30 °C) Max(1) (3 V) Unit tLDO(2) SMPS to LDO transition time Range 2 (EPOD booster OFF) 17.9 21 µs Range 2 (EPOD booster ON) 16.6 21 Range 1 (with EPOD booster ON) 15.6 19 tSMPS(2) LDO to SMPS transition time Range 2 (EPOD booster OFF) 14.6 17 µs Range 2 (EPOD booster ON) 13.4 16 Range 1 (with EPOD booster ON) 16.5 19 tVOST (without EPOD booster) Range 1 to range 2 LDO 5.3 8.7 µs SMPS 3.6 4.7 Range 2 to range 1 LDO 19.5 22 SMPS 26.2 31 tVOST (with EPOD booster) Range 1 to range 2 LDO 4.4 7.3 µs SMPS 2.8 3.7 Range 2 to range 1 LDO 18.9 23 SMPS 25.1 23 1. Evaluated by characterization and not tested in production. Temperature range from -40°C to 110°C. 2. Time to PWR_SVMSR.REGS change Table 70. Wake-up time using USART/LPUART Symbol Parameter Typ Max(1) Unit tWUUSART/ tWULPUART Wake-up time needed to calculate the maximum USART/LPUART baudrate allowing to wake up from Stop mode when USART/LPUART clock source is HSI16/MSI - (2) µs 1. Guaranteed by design. 2. This wakeup time is HSI16 or the MSI oscillator maximum startup time 5.3.8 External clock timing 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 5.3.14: I/O port characteristics. However, the recommended clock input waveform is shown in the figure below. Table 71. High-speed external user clock characteristics Specified by design and not tested in production. Symbol Parameter Conditions Min Typ Max Unit fHSE_ext User external clock source frequency Digital mode (HSEYBYP = 1, HSEEXT = 1) - - 50 MHz Analolog mode (HSEYBYP = 1, HSEEXT = 0) 4 - 50 VHSEH OSC_IN input pin high-level voltage Digital mode (HSEYBYP = 1, HSEEXT = 1) 0.7 × VDD - VDD V VHSEL OSC_IN input pin low-level voltage Digital mode (HSEYBYP = 1, HSEEXT = 1) VSS - 0.3 × VDD tw(HSEH) tw(HSEL) OSC_IN high or low time Digital mode (HSEYBYP = 1, HSEEXT = 1), voltage scaling range 1 7 - - ns Digital mode (HSEYBYP = 1, HSEEXT = 1), voltage scaling range 2 18 - - STM32U375xx Electrical characteristics DS14861 - Rev 2 page 124/222 |
