Evaluation board delivers “lowest power sensor-to-cloud IoT solution”

Fabless semiconductor company, InnoPhase IoT has integrated STMicroelectronics’ STM32U5 microcontroller in its InnoPhase IoT Talaria TWO Wi-Fi/ Bluetooth Low Energy evaluation board. According to the company, it enables more than 10 years of battery life for a variety of applications.

The board seamlessly integrates a low power Wi-Fi/BLE with the microcontroller to enable what is claimed to be the industry’s lowest power, cloud-connected battery-powered IoT devices. Target applications for the combination include wearables, industrial IoT, medical, commercial, and smart home automation

The STM32U5 is based on an Arm Cortex-M33 core and is a new generation of 32-bit microcontroller targeting the most demanding power/performance requirements. The microcontroller integrates the Cortex-M33 core with up to 4Mbyte of flash memory and 2.5Mbyte of SRAM, while cutting power by up to 90 per cent and extending battery life using power management features.

The InnoPhase IoT Talaria TWO Wi-Fi/BLE5 multi-protocol wireless platform enables the development of low power cloud connectivity applications using what is believed to be the industry’s lowest Tx current of 81ma at MCS7 and DTIM-10 current at 57 microA extends battery life to 10-plus years for IoT devices. Talaria TWO features Wi-Fi provisioning using Bluetooth Low Energy, secured over-the-air updates, and seamless cloud connectivity to AWS and Microsoft Azure for ease of development and deployment for IoT solutions, said InnoPhase. The high integration, small size, and multiple antenna options allow customers to meet new use case requirements, continued the company.

The seamless integration of STM32U5 and Talaria TWO evaluation boards allows designers to build low power sensor-to-cloud connected IoT solutions. Software integration is provided via ST’s I-CUBE-T2 software expansion for STM32Cube. The host application on STM32U5 uses the InnoPhase IoT Host APIs (HAPI) and communicates with the application running on the InnoPhase IoT Talaria TWO device. The kit supports AWS IoT services.

“Untethered, long battery life devices with direct cloud connectivity are unleashing the potential of IoT in multiple markets,” said InnoPhase IoT President and COO Wiren Perera.  

The STM32U5 microcontroller and Talaria TWO Wi-Fi/BLE SoC/Modules are currently in production. The STM32U5 NUCLEO-U575Z1-Q evaluation board and InnoPhase IoT’s Talaria TWO EVB-A (INP3014/INP3015) evaluation kits are available now to order. Talaria TWO Wi-Fi/BLE modules are certified with the Wi-Fi Alliance and Bluetooth SIG and have global regulatory certification.
