Additional Infomation About Product

STKNX Datasheet Miniature KNX transceiver with voltage regulators and microcontroller support Features Very thin fine pitch 4 x 4 mm VQFNPN24 package KNX certified, KNX TP1-256 supported Easy interface to microcontroller Very small system solution Two integrated voltage regulators for external use in application Selectable 3.3 V / 5 V - 20 mA linear regulator VFQFPN24 (4 x 4 x 1.0 mm, 0.5 mm Adjustable 1 V to 12 V - 150 mA high- efficiency DC/DC step down pitch) switching converter KNX bus power extractor supporting bus current up to 30 mA Adjustable KNX bus current slew rate dI/dt No crystal required Operating temperature range -40 C to +85 C Applications KNX twisted pair network (KNX TP1-256) Description The STKNX is a transceiver device for KNX TP communication. The small package and few external components enable very compact KNX node design. Product status link The simple interface to the microcontroller allows easy replacement of physical layer discrete component implementations. STKNX The STKNX device features two integrated voltage regulators for external use in the Product summary application: the selectable 3.3 V / 5 V - 20 mA linear regulator and the adjustable 1 V to 12 V - 150 mA high-efficiency DC/DC step down switching converter. Order code STKNX STKNXTR The integrated KNX bus power extractor supports bus current up to 30 mA to power Package VFQFPN24 external devices and the STKNX transceiver s own power needs, while limiting the Packing Tube Tape & Reel bus current slew rate according to KNX specifications. The STKNX ensures safe coupling to the bus and provides the bus monitoring Product label warning for the loss of bus power.
