LSE crystal/ceramic resonator oscillator
The LSE clock can be supplied with a 32.768 kHz crystal/ceramic resonator oscillator. All
the information given in this paragraph is based on characterization results with specified
typical external components. In the application, the resonator and the load capacitors have
to be placed as close as possible to the oscillator pins in order to minimize output distortion
and startup stabilization time. Refer to the crystal resonator manufacturer for more details
(frequency, package, accuracy...).

1.
C=CL1=CL2 is approximately equivalent to 2 x crystal CLOAD.
2.
The oscillator selection can be optimized in terms of supply current using a high quality resonator with a small Rm value.
Refer to crystal manufacturer for more details.
3.
Guaranteed by design. Not tested in production.
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.
