Smart Metering

The EFR32FG23 Flex Gecko SoC is an ideal solution for sub-GHz IoT wireless connectivity for smart home, security, lighting, building automation, and metering. The high-performance sub-GHz radio provides long range and is not susceptible to 2.4 GHz interference from technologies. The single die, multi-core solution, provides industry leading security, low power consumption with fast wakeup times, and an integrated power amplifier to enable the next generation of secure connectivity for IoT devices.

The EFR32FG28 SoC is an ideal dual band Sub-GHz + 2.4 GHz Bluetooth LE SoC solution for IoT applications in smart homes, security, lighting, building automation, and metering. This dual band solution combines a high-performance Sub-GHz radio that provides long range capabilities and a Bluetooth radio for increased design flexibility. The large memory footprint and increased IO count allows for design consolidation and Secure Vault™ gives flexibility to choose the security level that meets your product’s needs.

EFR32FG25 wireless SoCs are an ideal solution for long range, Sub-GHz wireless connectivity for smart metering, lighting, city and building automation. The inclusion of multi-rate OFDM, FSK, and O-QPSK modulation schemes allows for data rates up to 3.6 Mbps while keeping immunity to 2.4 GHz interference. The large memory footprint and increased IO count allows for design consolidation and when combined with Secure Vault™ can provide higher level system security.

Silicon Labs' RS9116 QMS wireless SoCs with single band provide a comprehensive multi-protocol wireless connectivity solution including 802.11 b/g/n (2.4 GHz), dual-mode Bluetooth 5. The wireless SoCs offers high throughput, extended range with power-optimized performance. The wireless SoCs are FCC, IC, and ETSI/CE certifiable.

Our SiWx917M SoC is our lowest power Wi-Fi 6 SoC, ideal for ultra-low power IoT wireless devices using Wi-Fi®, Bluetooth, Matter, and IP networking for secure cloud connectivity. It is optimal for developing battery operated devices that need long battery life. SiWx917M SoC includes an ultra-low power Wi-Fi 6 and Bluetooth Low Energy LE 5.4 wireless CPU subsystem, and an integrated micro-controller (MCU) application subsystem, security, peripherals and power management subsystem all in a single 7x7 mm QFN package. The wireless subsystem consists of a Network Wireless Processor running up to 160 MHz, baseband digital signal processing, analog front end, 2.4 GHz RF transceiver and integrated power amplifier. The application subsystem consists of an ARM® Cortex®-M4F running up to 180 MHz, embedded SRAM, FLASH, and Sensor Hub. The ARM® Cortex®-M4F is dedicated for peripheral and application-related processing, while the network wireless processor runs the wireless and networking stacks on independent threads, thus providing a fully integrated solution that is ready for a wide range of embedded wireless IoT applications.

Target applications include Smart Homes, Consumer Health and Wearables, Medical, Industrial, Retail, Smart Building and Cities, Asset Tracking.

The EFP01 Energy Friendly Power Management IC (PMIC) is an extremely flexible, highly-efficient, multi-output power management IC, providing complete system power and primary cell battery Coulomb counting for EFM32 and EFR32 devices. These devices operate over a wide input voltage range (0.8 to 5.5 V) with quiescent current as low as 150 nA. EFP01 provides three voltage output rails and four supply outputs – 1x buck/boost converter, 1x buck-only DC-DC converter + LDO, 1x LDO and 1x switched – delivering up to 94% efficiency.
