I used an LSE component proven out on another design containing a STM32F412 for a new design using a STM32L433. The LSE part is Abracon ABS06-32.768kHz-6 which is listed in AN2867 as compatible with the L4 family. I'm using the HAL_RCCEx_EnableLSCO()...

I am developing on a STM32L4 product and was having issues with the CSS shutting down my LSE signal. I found this problem in the errata and turned the CSS off, but it forced me to look closer at the signal my LSE crystal was providing (using the LSCO...

My CLs are 6.8pF. I tried lowering them without a noticeable difference in my output signal.

I have tied every mode level, and they all gave about the same response. technically driving at anything about LOW will meet the gmcrit criteria. When I measure the piped out value of my LSE signal my average frequency is close to expected, but the r...

By delayed, i don't mean the signal itself had a noticeable delay, just that the output didn't immediately match my Oscillator input until later in the day or the next morning. I do not have a battery installed in my VBAT connector at the moment. I d...

Why does my LSCO output for my LSE have a delay in matching my LSE input.
