TP-UART 2

TPUART2

The TP-UART 2 is the next generation of KNX transceiver. It is digitally compatible with its predecessor so that communication stacks and drivers can be used without modification.
It offers enhanced features including efficient stabilized 3.3 V and 5 V power supply with 30 mA maximum current (50 mA when 20 V not used), switchable 20 V power supply with limiting function and a smaller QFN 36 package.

Package: QFN 36
Available current for bus powered devices: 50 mA @ 3.3 V or 5 V, 25 mA @ 20 V


TP-UART 2 evaluation board

The TP-UART 2 evaluation board offers an interface to the KNX bus together  with a Bus Transceiver Interface (BTI) for quick development of your applications based on TP-UART 2.


TP-UART

The TP-UART contains the physical coupling to the KNX bus. The communication system is done via a standard UART Interface. The TP-UART was developed to relieve the microcontroller of the bit coding and decoding duty on the one hand and to allow the coupling to KNX through different microcontrollers on the other hand.

Package: SOIC 20
Available current for bus powered devices: 10 mA @ 5 V


FZE1066

The FZE1066 transceiver offers a bit-interface between the KNX bus and the application microcontroller. It is designed according the KNX specification so that development using the FZE1066 can be easily certified.

Package: SOP 20
Available current for bus powered devices: 30 mA @ 5 V & 5 mA @ 20 V
