NXP Semiconductors LPC18Sx ARM® Cortex® Mikrocontroller
Die LPC18Sx-Familie von NXP Semiconductors enthält ARM-Cortex®-M3-basierte Mikrocontroller mit Sicherheitsfunktionen für eingebettete Anwendungen. Der ARM Cortex-M3 enthält einen Kern der nächsten Generation, der Systemverbesserungen wie niedrigen Energieverbrauch, verbesserte Debug-Funktionen und ein hohes Maß an Support Block Integration bietet. Die ARM Cortex-M3 CPU integriert eine dreistufige Pipeline und arbeitet an CPU-Frequenzen bis 180MHz. Die Harvard-Architektur bietet separate lokale Anweisungs- und Daten-Busse sowie einen dritten Bus für Peripheriegeräte. Außerdem besitzt die ARM Cortex-M3 CPU eine interne Prefetch Unit, die Speculative Branching unterstützt. Die LPC18Sx ARM Cortex-M3 basierten Mikrocontroller bieten bis zu 200kB On-Chip-SRAM, Sicherheitsfunktionen mit einer AES-Engine, eine Vierfach-SPI-Flash-Schnittstelle (SPIFI), ein statuskonfigurierbares Timer/PWM-Untersystem (SCTimer/PWM), zwei High-Speed-USB-Controller, Ethernet, LCD, einen externen Speichercontroller und viele digitale und analoge Peripheriegeräte.Merkmale
