STMicroelectronics Miniature KNX Transceiver with Voltage Regulators TP1-256 for KNX TP Communication STKNXTR

The STMicroelectronics STKNX miniature KNX transceiver is a device used for KNX TP communication is housed in a small 4mmx4mm VQFNPN24 package for compact designs. The simple interface to the μC allows easy replacement of physical layer discrete components implementations. The STKNX features two integrated voltage regulators for external use in the application which includes a selectable 3.3V/5V - 20mA linear regulator and an adjustable 1V to 12V - 150mA high-efficiency DC/DC step down switching converter. It is used in KNX twisted-pair networks.
