The crystal motional resistance Rm relates to the equivalent series resistance (ESR) by the following formula:
Measured with the load capacitance specified by the crystal manufacturer. If CXIN = CXOUT = 10 pF, CL = 5 pF. Parasitic capacitance
from the package and board must also be considered.
When selecting a crystal, the system design must consider the temperature and aging characteristics of a
crystal versus the user environment and expected lifetime of the system.
Table 11-5 and Table 11-6 list the switching characteristics of the oscillator and the timing requirements of
the 32.768-kHz input clock. Figure 11-6 shows the crystal oscillator output in normal mode.

11.2.3.2 External Clock Description
When an external 32K clock is used instead of a crystal, three configuration can be used:
A square- or sine-wave input can be applied to the 32KXIN pin with amplitude of 1.85 or 1.8 V. The
32KXOUT pin can be driven to a dc value of the square- or sine-wave amplitude divided by 2. This
configuration, shown in Figure 11-7, is recommended if a large load is applied on the 32KXOUT pin.
A square- or sine-wave input can be applied to the 32KXIN pin with amplitude of 1.85 or 1.8 V. The
32KXOUT pin can be left floating. This configuration, showed in Figure 11-8, is used if no charge is
applied on the 32KXOUT pin.
The oscillator is in bypass mode and a square-wave input can be applied to the 32KXIN pin with
amplitude of 1.8 V. The 32KXOUT pin can be left floating. This configuration, shown in Figure 11-9, is
