151 / 270 page  DS14258 Rev 5 151/270 STM32H562xx and STM32H563xx Electrical characteristics 238 manufacturer for more details on the resonator characteristics (frequency, package, accuracy). Note: For information on selecting the crystal, refer to AN2867 “Guidelines for oscillator design on STM8AF/AL/S and STM32 MCUs/MPUs”, available from www.st.com. Figure 30. Typical application with a 32.768 kHz crystal Note: An external resistor is not required between OSC32_IN and OSC32_OUT, and it is forbidden to add one. Table 43.

Refer to the note and caution paragraphs below the table, and to AN2867 “Guidelines for oscillator design on STM8AF/AL/S and STM32 MCUs/MPUs”. 3. tSU(LSE) is the startup time measured from the moment it is enabled (by software) to when a stabilized 32.768 kHz oscillation is reached. This value is measured for a standard crystal and can vary significantly with the crystal manufacturer ai17531d STM32 OSC32_OUT fLSE CL1 RF 32.768 kHz resonator Bias controlled gain OSC32_IN CL2 Resonator with integrated capacitors |
