Low-speed external clock source AC timing diagram
High-speed external clock
The high-speed external (HSE) clock can be supplied with a 4 to 16 MHz crystal/ceramic
resonator oscillator. All the information given in this paragraph are based on characterization
results obtained with typical external components specified in Table 21. 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 on the resonator characteristics (frequency,
package, accuracy).

1.
Resonator characteristics given by the crystal/ceramic resonator manufacturer.
2.
For CL1 and CL2 it is recommended to use high-quality ceramic capacitors in the 5 pF to 25 pF range (typ.), designed for
high-frequency applications, and selected to match the requirements of the crystal or resonator. CL1 and CL2, are usually
the same size. The crystal manufacturer typically specifies a load capacitance which is the series combination of CL1 and
CL2. PCB and MCU pin capacitance must be included when sizing CL1 and CL2 (10 pF can be used as a rough estimate of
the combined pin and board capacitance).
3.
The relatively low value of the RF resistor offers a good protection against issues resulting from use in a humid
environment, due to the induced leakage and the bias condition change. However, it is recommended to take this point into
account if the MCU is used in tough humidity conditions.
4.
Based on characterization results, not tested in production.
5.
tSU(HSE) is the startup time measured from the moment it is enabled (by software) to a stabilized 8 MHz oscillation is
reached. This value is measured for a standard crystal resonator and it can vary significantly with the crystal manufacturer
