Silicon Labs EFM32 Pearl Gecko MCUs
Die Silicon Labs Pearl Gecko-Familie von 32-Bit Mikrocontrollern (MCU) bietet einen leistungsstarken 32-Bit ARM® Cortex®-M3 und eine Palette von Peripheriegeräten. Die Peripheriegeräte umfassen eine einzigartige kryptografische Hardware-Engine, die AES, ECC und SHA unterstützt. Die Pearl Gecko 32-Bit Mikrocontroller umfassen auch einen Aktivmodus mit äußerst geringem Stromverbrauch und einer kurzen Aktivierungszeit aus Energiesparmodi. Die Pearl Gecko Mikrocontroller eignen sich hervorragend für batteriebetriebene Applikationen und andere Systeme, bei denen eine hohe Leistungsfähigkeit und ein geringer Stromverbrauch erforderlich ist.
Silicon Labs offer EFM32PG12 Pearl Gecko MCUs which combine very low active current consumption, enhanced sleep mode capabilities, and integrated security features. This enables the next generation of secure, battery-operated IoT products. A large 1MB flash with dual-bank architecture and in-field update capability enables even richer applications that can be updated after product deployment.
