System Parameters
The following parameters specify several aspects which are important when integrating
the XC228xH into an application system.
Note: These parameters are not subject to production test but verified by design and/or
characterization.
Note: Operating Conditions apply.

1) The short-term frequency deviation refers to a timeframe of 20 ms and is measured relative to the current
frequency at the beginning of the respective timeframe
2) This parameter is tested for the fastest and the slowest selection. The medium selections are not subject to
production test - verified by design/characterization
3) f_WU in MHz
4) This value includes a hysteresis of approximately 50 mV for rising voltage.
