1) Functional isolation! The isolation is bridged by an RC filter for EMC reasons. Safety agency hazardous
voltage barrier requirements are not supported!
2) Functional isolation! The isolation is bridged by a 300 V varistor for protection of the device. Safety agency
hazardous voltage barrier requirements are not supported!
3) The data retention time of the Flash memory depends on the temperature. Longer storage periods (weeks) at
higher temperatures should be avoided.
