NCN51205GEVB
KNX Evaluation Board
User'sManual
Introduction
The NCN5120 Development Board is the ideal solution
for developing your KNX application with the
ON Semiconductor KNX transceiver NCN5120. The
development board contains the NCN5120 KNX
Transceiver which handles the transmission and reception of
data on the bus. It will also generate all necessary voltages
to power the board and external loads.
It also contains a microcontroller with debug interface for
custom firmware development. Up to 8 external switches
can be monitored and up to 4 external loads can be
controlled. A voltage between 3.3 V and 21 V is available to
drive the external loads.
The NCN5120 Development Board assures safe coupling
to and decoupling from the KNX bus. Bus monitoring warns
the external microcontroller for loss of power so that critical
data can be stored in time.
