California-based InnoPhase IoT has selected Swiss firm ST Microelectronics to deliver low-power sensor-to-cloud IoT technology to provide ten years battery life on its evaluation boards,

This sees the seamless integration of the STM32U5 MCU and InnoPhase IoT Talaria Two wifi evaluation boards.

InnoPhase IoT is a fabless semiconductor company specialising in low-power wifi IoT. Its evaluation platform combines STM’s STM32U5 MCU evaluation board with InnoPhase IoT’s Talaria Two wifi and Bluetooth LE evaluation board. Target applications for the combination include wearables, industrial IoT, medical, commercial and smart-home automation.

The MCU is based on an Arm Cortex-M33 core and is a 32bit microcontroller that integrates up to 4Mbyte of flash memory and 2.5Mbyte of SRAM, while cutting power by up to 90% and extending battery life using power-management features.

The Talaria Two multiprotocol wireless platform enables the development of low-power cloud-connectivity applications without compromising performance. The Tx current of 81mA at MCS7 and DTIM-10 current at 57µA extends battery life to ten-plus years for IoT devices.

Talaria Two features wifi provisioning using BLE, secured over-the-air updates, and seamless cloud connectivity to AWS and Microsoft Azure, providing ease of development and deployment for IoT.

The integration of the STM32U5 and Talaria Two evaluation boards lets designers build low-power sensor-to-cloud connected IoT offerings. Software integration is provided via STM’s I-Cube-T2 software expansion for STM32Cube. The host application on STM32U5 uses the InnoPhase IoT host APIs and communicates with the application running on the Talaria Two device. The kit supports AWS IoT services.

“InnoPhase IoT Talaria Two’s low-power wifi connectivity to STM32U5 offers long battery life for ultra-low-power smart applications, including wearables, personal medical devices, home automation and industrial IoT,” said Bertrand Denis, product manager at ST Microelectronics (www.st.com). “Our collaborating with InnoPhase IoT will help customers meet low-power, long battery-life requirements without sacrificing performance while implementing wifi cloud connectivity.”

Wiren Perera, InnoPhase IoT COO, added: “Untethered, long battery life devices with direct cloud connectivity are unleashing the potential of IoT in multiple markets. The combination of STM’s lowest-power MCU, the STM32U5, with our industry’s lowest-power wifi and BLE option delivers a platform enabling rapid time-to-development and deployment utilising ubiquitous wifi connectivity for our customers.”

The STM32U5 MCUs and Talaria Two SoCs and modules are in production. Talaria Two modules are certified with the Wifi Alliance and Bluetooth SIG and have global regulatory certification.

InnoPhase IoT (innophaseiot.com), headquartered in San Jose, California, is a fabless wireless semiconductor platform company dedicated to the IoTs. Its flagship product, the Talaria Two multiprotocol chipset and modules deliver low-power wifi radio to the untethered battery-operated IoT device market.
