System Parameters
The following parameters specify several aspects which are important when integrating
the XC228xM into an application system.
Note: These parameters are not subject to production test but verified by design and/or
characterization.

1) The limit V_LV - 0.10 V is valid for the OK1 level. The limit for the OK2 level is V_LV - 0.15 V.
2) This value includes a hysteresis of approximately 50 mV for rising voltage.
3) 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.
The short-term deviation with the duration of a LIN-frame allows error-free transmission.
