NCN5120

ntroduction
NCN5120 is a receiver−transmitter IC suitable for use in KNX
twisted pair networks (KNX TP1−256). It supports the connection of
actuators, sensors, microcontrollers, switches or other applications in
a building network.
NCN5120 handles the transmission and reception of data on the bus.
It generates from the unregulated bus voltage stabilized voltages for its
own power needs as well as to power external devices, for example, a
microcontroller.
NCN5120 assures safe coupling to and decoupling from the bus.
Bus monitoring warns the external microcontroller in case of loss of
power so that critical data can be stored in time.
