107 / 165 page  DS11929 Rev 3 107/165 STM32WB55xx Electrical characteristics 152 6.3.10 External clock source characteristics High-speed external user clock generated from an external source The high-speed external (HSE) clock must be supplied with a 32 MHz crystal oscillator. The STM32WB55xx include internal programmable capacitances that can be used to tune the crystal frequency in order to compensate the PCB parasitic one. The characteristics in Table 52 and Table 53 are measured over recommended operating conditions, unless otherwise specified. Typical values are referred to TA = 25 °C and VDD = 3.0 V. Table 51. Wakeup time using LPUART(1) Symbol Parameter Conditions Typ Max Unit tWULPUART Wakeup time needed to calculate the maximum LPUART baud rate allowing to wakeup up from Stop mode when LPUART clock source is HSI16 Stop mode 0 - 1.7 µs Stop mode 1/2 - 8.5 1. Guaranteed by design. Table 52.
