ST Expands Wireless SoC Family to 'Support All Sub-GHz Standards'
Published2020.12.15 12:05Reveals addition of flexible configuration and package options
Supports (G)FSK, (G)MSK, BPSK modulation, etc.
STMicroelectronics announced on the 15th that it has expanded availability to support a wide range of applications by adding flexible configurations and package options to the STM32WL long-range sub-GHz wireless SoC family. Connecting with LoRa®-based low-power LPWAN (Low-Power Wide-Area Network) devices, the STM32WL series is suitable for developing low-power, high-reliability, ultra-compact IoT devices.
LPWAN expands the communication range of IoT by providing cost-effective connectivity across wide areas and remote locations. Furthermore, it enables the creation of greater value in various industrial sectors, ranging from utilities and agriculture to shipping and transportation, through smart technologies.
The STM32WL series integrates ST's STM32 ultra-low power MCU architecture with a sub-GHz wireless subsystem that supports multiple modulation schemes. It includes (G)FSK, (G)MSK, and BPSK modulations used in LoRa, Sigfox, and wM-Bus (wireless Meter-Bus), which provide high reception sensitivity at low RF signal power, as well as other proprietary protocols and sub-GHz standards.
The newly released dual-core STM32WL55 is based on Arm® Cortex®-M4 and Cortex-M0+ MCU cores and can be used in a completely open and flexible manner. The dual-core architecture ensures hardware isolation that enhances cybersecurity. With new wireless products, application updates are possible without re-certifying the device, and real-time performance is improved.
The STM32WL55 was added to the single-core STM32WLE5 line, released in January 2020 in BGA73 and QFN48 packages. It uses a main Cortex-M4 core to handle wireless and applications. The expanded lineup also includes two LoRa-free products, the single-core STM32WLE4 and the dual-core STM32WL54, allowing developers to flexibly utilize them for new wireless IoT projects.
All devices are supported by ST's 10-year product supply warranty for industrial products.

LTE Cat M1's cellular features make it ideal for IoT.
When developing IoT solutions, engineers must carefully consider how to connect to the internet. LTE Cat M1 is a cellular network that, along with LoRa and NB-IoT among LPWAN technologies, can be used not only in short-range but also in long-range applications. Unlike standard LTE, it offers limited capacity but at a lower cost.
