Wireless SoCs for high-performance and low-power IoT applications

Mouser Electronics, Inc. now stocks the EFR32xG29 Series 2 Wireless SoCs from Silicon Labs. These wireless SoCs, including the EFR32MG29 and EFR32BG29, are advanced multi-protocol and BLE-optimised wireless solutions for high-performance, low-power IoT devices. The EFR32BG29 SoC is suited to wearable medical devices, asset monitoring, and power tools, while the EFR32MG29 SoC is designed for security systems, smart homes, and building automation.

The wireless SoCs support Zigbee, Thread, BLE, and proprietary 2.4GHz protocols. With up to 1024KB of Flash memory and 256KB of RAM, these wireless SoCs include sufficient memory for complex applications and over-the-air updates. The SoCs feature a powerful Arm Cortex-M33 with TrustZone technology that delivers efficient processing and enhanced security. Integrated features, including a high-performance radio with +20dBm output power and low-energy sensor interfaces, ensure reliable connectivity and help to extend battery life.

The wireless SoCs also offer a selection of MCU peripherals, including an ADC, an eight-channel DMA controller, and a watchdog timer. The SoCs support buck and boost DC-DC converters. The buck DC-DC is ideal for devices running on batteries with a 1.8V to 3.8V voltage range, while the boost DC-DC operates from 1.2V to 1.7V and is suitable for devices with a smaller form factor or lower-cost batteries. To protect IoT devices against remote and local cyberattacks, the SoCs feature Secure Vault High with hardware cryptographic acceleration, TRNG, secure boot, and other advanced security features. The EFR32xG29 Series 2 Wireless SoCs are supplied in a 5mm x 0.85mm x 0.4mm QFN40 package. The EFR32BG29 variant is also available in an ultra-compact WLCSP45 package.

The Silicon Labs ERF32BG29 and ERF32MG29 development boards enable developers to profile energy usage, debug applications, and analyse wireless network behaviour. The featured radio boards can be used with either a Wireless Starter Kit Mainboard (BRD4001A) or a Wireless Pro Kit Mainboard (BRD4002A).
