What are the recommended CL and maximum ESR for a 32kHz crystal, on the STM32F103RB?

For example, is CL=12.5pF and ESR=35kOhm okay?

Dear espresso_solo,

Generally these values depend on the Quartz manufacturers, you can refer to our Application Note

and also to the STM32 Datasheets

or

, Section : Operating conditions then then External clock source characteristics For more details.

With best regards,
