The EZR32LG and EZR32WG devices are available with a choice of EZRadio and EZRadioPRO transceivers to accommodate an array of RF performance requirements. The EZRadio versions meet the needs of most simple and cost-sensitive 'button-press' wireless designs such as remote controls, garage door openers and other point-to-point network configurations. The EZRadioPRO versions target applications requiring cutting-edge radio features and higher RF performance to support ultra-long-range narrowband connectivity and complex packet formats and network protocols. The powerful EZRadioPRO transceiver architecture supports advanced packet processing and modem functionality such as automatic frequency compensation (AFC), preamble detection and automatic gain control (AGC) as well as frequency hopping.

Simplifying wireless development

The enhanced Simplicity Studio development environment, now supporting concurrent MCU and wireless design, provides a comprehensive, easy-to-use platform for developing wireless applications based on the EZR32 family. Simplicity Studio supports the Silicon Labs Connect software stack, a fully tested connectivity solution for point-to-point and star network topologies. Silicon Labs Connect abstracts the lower-level details of sub-GHz protocols and configuration, freeing designers to focus on application development. Silicon Labs also offers a choice of cost-effective EZR32 Wireless Starter Kits, providing all of the hardware and software tools developers need to evaluate and develop sub-GHz wireless applications. Hardware tools include an on-board debugger, advanced energy monitoring and integrated packet trace. Simplicity Studio, including all documentation and sample applications, is available for download at no charge at

Samples and production quantities of the EZR32LG and EZR32WG wireless MCUs are available in a space-saving 9mm x 9mm 64-pin QFN package. EZR32LG pricing begins at $2.71, and EZR32WG pricing begins at $2.98, both in 10,000-unit quantities. The SLWSTK62xxA starter kits, supporting various MCU and radio configurations, are priced at $299.
