适用于 Zigbee 和 Thread 的 EM359x 片上系统 (SoC) 和网络协处理器

EM359x devices for Zigbee and Thread are the industry’s leading ARM® Cortex®-M3 based family of mesh networking SoCs, delivering unmatched performance, power consumption and code density in a compact package. EM359x SoCs combine a 2.4 GHz IEEE 802.15.4 radio transceiver with a 32-bit microprocessor, flash memory and RAM with powerful hardware-supported, network-level debugging features. Tightly integrated with our Zigbee and Thread mesh networking service, these devices and mesh networking tools simplify development and accelerate time to market.

Due to the evolution of the Zigbee protocol, Flash and RAM requirements have increased.  We recommend migrating to EFR32MG devices with more Flash and Memory to future proof designs:

  • EFR32MG13 for battery-powered Zigbee or Thread applications
  • EFR32MG12 for Zigbee, Thread and multiprotocol applications
  • EFR32MG21 for mains powered mesh applications including lighting, gateways and voice assistants
