Note:
For information on selecting the crystal refer to application note AN2867 “Oscillator design
guide for STM8S, STM8A and STM32 microcontrollers” available from www.st.com.
Figure 16. Typical application with a 32.768 kHz crystal
Note:
No external resistors are required between OSC32_IN and OSC32_OUT, and it is forbidden
to add one.
In bypass mode the LSE oscillator is switched off and the input pin is a standard GPIO.
The external clock signal has to respect the I/O characteristics detailed in Section 6.3.16.
The recommend clock input waveform is shown in Figure 17.
Figure 17. Low-speed external clock source AC timing diagram
1. Specified by design, not tested in production.
2. tSU(LSE) is the startup time measured from the moment it is enabled (by software) until a stable 32 kHz oscillation is
reached. This value is measured for a standard crystal and it can vary significantly with the crystal manufacturer.
