Abstract: Data exchanges between an ultra-wide band communication module and a secure element are controlled such that the data exchanges pass through a near-field communication router. The near-field communication router controls routing of the data exchanges so that the data exchanges do not pass through a host circuit that is also coupled to the near-field communication router.

Abstract: In some embodiments, a contactless communication device includes an antenna, and a driving stage having a power supply terminal configured to receive a power supply voltage, where the driving stage is configured to deliver a current to the antenna. The device further includes a monitoring circuit configured to monitor the power transmitted by the antenna. The monitoring circuit is configured, in the presence of a request for a reduction in a current level of transmitted power, to reduce the power supply voltage of the driving stage down to a target value corresponding to a new level of the transmitted power less than the current level.
