SuperNEMO is the next-generation (0νββ) experiment based on a tracking plus calorimetry technique. The demonstrator is made of a calorimeter (712 channels) and a tracking detector (6102 channels). These detectors front-end electronics use an unified architecture. The trigger system has for the calorimeter part 2 trigger thresholds, for the tracker part the possibility of a second triggering for a delayed particle. The calorimeter and tracker can operate separately. We have an overlap between the zoning of the calorimeter and the tracker. The final trigger decision is made considering spatial coincidences between hits from the calorimeter and tracker detectors.
