Silicon Labs Ember EM351/EM357 ARM SoCs
Silicon Labs Ember EM351/EM357 ARM SoCs with integrated Zigbee chips deliver unmatched performance, power consumption, and code density in a compact package. These SoCs combine a 2.4GHz IEEE 802.15.4 radio transceiver with a 32-bit ARM® Cortex-M3 microprocessor, Flash, and RAM memory with powerful hardware-supported network-level debugging features. Combined with the powerful ecosystem of ARM tools, these devices and tools enable OEMs to simplify development and accelerate time-to-market. The EM351 and EM357 SoCs are tightly integrated with EmberZNet PRO, a ZigBee-compliant mesh networking software. The Silicon Labs EM35x chips can be designed in as full SoC devices for low cost, low power sensors, and other devices in the home. Also for Network Co-processor (NCP) devices as more complex applications running on a large applications microprocessor.Features
