Figure 5-20. WKUP_LFOSC0 Crystal Implementation
NOTE
The load capacitors, Cf1 and Cf2 in Figure 5-21, should be chosen such that the below
equation is satisfied. CL in the equation is the load specified by the crystal manufacturer. All
discrete components used to implement the oscillator circuit should be placed as close as
possible to the associated oscillator WKUP_LFOSC0_XI, WKUP_LFOSC0_XO, and VSS
pins.
Figure 5-21. Load Capacitance Equation
The crystal must be in the fundamental mode of operation and parallel resonant. Table 5-28 summarizes
the required electrical constraints

When selecting a crystal, the system design must consider the temperature and aging characteristics of a
based on the worst case environment and expected life expectancy of the system.
Table 5-29 details the switching characteristics of the oscillator and the requirements of the input clock.
