EM34x Zigbee Remote Control ICs - SoCs

EM34x Zigbee Remote Control IC

EM341 is a fully integrated system-on-chips (SOC) that integrate a 2.4 GHz, IEEE 802.15.4-2003-compliant transceiver, 32-bit ARM® Cortex®-M3 microprocessor, flash and RAM memory and peripherals of use to designers of Zigbee-based RF4CE systems. The integrated receive channel filtering allows for robust co-existence with other communication standards in the 2.4 GHz spectrum, such as IEEE 802.11-2007 and Bluetooth®. The integrated 32-bit ARM Cortex-M3 microprocessor is highly optimized for high performance, low power consumption, and efficient memory utilization.

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
