217 / 340 page  DS12737 Rev 6 217/340 STM32L552xx Electrical characteristics 307 Note: For information on selecting the crystal, refer to the application note AN2867 “Oscillator design guide for ST microcontrollers” available from the ST website www.st.com. Figure 36. 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 89. LSE oscillator characteristics (fLSE = 32.768 kHz)(1) 1. Guaranteed by design. Symbol Parameter Conditions(2) 2. Refer to the note and caution paragraphs below the table, and to the application note AN2867 “Oscillator design guide for ST microcontrollers”.
