STMicroelectronics is helping increase industrial productivity and reduce waste and pollution with its smart wireless module. Conceived for Industry 4.0 applications, this module, the STM32WB5MMGH6, simplifies using ST’s innovative wireless microcontrollers in powerful use cases like I-care Group’s intelligent equipment condition monitoring.
The module provides a complete subsystem for wireless communication using popular standards such as Bluetooth Low Energy, Zigbee, and Thread and comes with free-to-use protocol stacks. Alternatively, developers can use other proprietary protocols, if preferred. The module integrates several essential components including the antenna and its matching circuitry, all the passives, and timing crystals. Pre-certifications for EMC, Bluetooth LE 5.3, Zigbee 3.0, and OpenThread simplify the mandatory testing and product-level approval processes for users, which saves development costs and accelerates time to market.
Lead customers are already building ST’s STM32WB5MMGH6 module into upcoming new products. One example is I-care Group, a global leader in machine health, whose continuous monitoring solutions enhance the maintenance of industrial equipment to ensure optimum performance and avoid unexpected failures and downtime. The Company’s Wi-care sensors are a true plug-and-play wireless and continuous asset monitoring system. When combined with I-see, I-care’s cloud-based and AI-driven analytical platform, it provides a complete maintenance 4.0 solution, allowing users to visualize equipment status and plan maintenance schedules. With I-care solutions, more than 99% of industrial breakdowns can be avoided, machine downtime is reduced by 10-20%, and maintenance costs are reduced by 35-45%.
The STM32WB55 MCU powering the STM32WB5MMGH6 has an Arm Cortex-M4 core for application-level processing and a Cortex-M0+ dedicated to managing the integrated radio, which safeguards real-time performance in both domains.
The MCU contains generous on-chip RAM, which is particularly advantageous when running the Thread protocol. Popular use cases include wireless communication and control of devices such as remote sensors, smart door locks, PC accessories including printers, and infrastructure equipment like network gateways and smart-building controllers. The radio’s multi-protocol technology provides flexibility and allows convenient device administration and fleet management.
Product designers working with the STM32WB5MMGH6 module benefit from the extensive STM32 microcontroller development ecosystem that includes free tools like the STM32CubeMX configurator and software like the STM32CubeWB MCU package. This package provides essential embedded-development resources, including production-ready MISRA C and ISO/TS 16949 compliant Hardware Abstraction Layer (HAL) and low-layer APIs, FatFS file system, FreeRTOS, communication-protocol stacks, and code examples.
The STM32WB5MMGH6TR is in production now and available for new designs, priced from $6 for orders of 10,000 pieces. It is supported by ST’s 10-year product longevity commitment, which ensures long-term availability of parts for industrial applications.
