All signal timing information is given for output pin load capacitances of 30pF, unless specified
otherwise.
Relaxation Oscillator
This table lists the performance characteristics of the relaxation oscillator over the full range of process
variation, operating temperature and supply voltage.

OSC
The Rext pin for the external resistor to set the frequency of the relaxation oscillator is available only on
the 208BGA package. On devices in this package, the relaxation oscillator frequency can be adjusted
over a range from 1MHz to 11MHz by changing the value of an external resistor connected from the
Rext pin to GND. In the smaller 68QFN and 100QFN packages, the relaxation oscillator runs at the
frequency corresponding to an open circuit at the Rext pin with the external resistor not fitted,
nominally 1MHz.
Crystal Oscillators
This table lists the performance characteristics of the low and high frequency oscillators over the full
range of process variation, operating temperature and supply voltage.
T
The crystal oscillator circuits require external load capacitors connected from both ends of the quartz
crystal to GND, as shown in Applications Information. The recommended load capacitor values are
10pF for the low reference oscillator and 22pF for the high reference oscillator.
