NXP Semiconductors Kinetis W Mikrocontroller

Der drahtlose Kinetis KW2x Mikrocontroller von Freescaleerweitert die erfolgreiche Kinetis-Mikrocontroller-Familie, die auf dem ARM Cortex-M4 CPU-Kern basiert. Der Kinetis KW2x integriert einen branchenführenden 2,4 GHz HF-Transceiver sowie einen ARM Cortex-M4-Kern und bietet stabile Funktionen für eine zuverlässige, sichere und energiesparende drahtlose IEEE 802.15.4-Lösung. Diese drahtlosen Mikrocontroller bieten bis zu 512 KB Flash, 64 KB RAM und bis zu 64 KB FlexMemory. Die duale PAN-Unterstützung ermöglicht dem System die gleichzeitige Teilnahme an zwei ZigBee-Netzwerken und macht so die Notwendigkeit von mehreren Funksystemen überflüssig. Software-Protokollstacks, Werkzeuge und IDE sind mit den Kinetis-Mikrocontrollern kompatibel. Die ZigBee-Protokoll-Software ist nahtlos in den Kinetis-Software-Entwicklungstools für eine schnelle Konstruktion von integrierten Systemen eingebunden. Zu den typischen Anwendungsbereichen gehören Heimnetzwerke, die aus Messgeräten, Gateways, Inhome-Displays und verbundenen Haushaltsgeräten bestehen sowie vernetzte Gebäudesteuerungs- und Heimautomatisierungsanwendungen mit Beleuchtungssteuerung, HVAC und Sicherheitsfunktionen.
