  1. Rev C silicon - VDD limited range = [3.0 - 5.0 V].
  2. Rev D silicon - full VDD range [2.7 - 5.5 V], by adjusting OSCCTRL.CAL48M. See Errata reference 15342.
  3. Applicable for all package types except the WLCSP, on which accuracy is degraded by ±1% from the current values.
  4. These are based on characterization.
  5. These are based on simulation. These values are not covered by test or characterization.
