LSE oscillator circuit diagram Internal clock sources Subject to general operating conditions for VDD, and TA. High speed internal RC oscillator (HSI) In the following table, data are based on characterization results, not tested in production, unless otherwise specified. 4. tSU(LSE) is the startup time measured from the moment it is enabled (by software) to a stabilized 32.768 kHz oscillation. This value is measured for a standard crystal resonator and it can vary significantly with the crystal manufacturer.
