Crystal Osc.
RC Osc.
The RC oscillator has a built-in capacitor. An external resistor is needed to connect from FXI to GND to
determine the oscillation frequency. The capacitance of internal RC oscillator is selected by mask option
MO_RCAP[2..0].

The following table shows the combinations of R and C, and the resulting frequency. Please note that
oscillation frequency in the table only represents oscillation frequencies of certain samples. The actual
oscillation frequency may vary up to
±
15% from lot to lot due to process parameter variations. User must
take this into consideration when using this chip in applications.

Two types of oscillator, crystal and RC, can be used as slow clock by mask option MO_SXTAL. If used
for time keeping function or other applications that required the accurate timing, crystal oscillator is
recommended. If the timing accuracy is not important, then RC type oscillator can be used to reduce cost.
