STMicroelectronics reveals
high-performance, state-of-the-art wireless microcontrollers ready
for incoming cyber-protection regulations
Highly integrated chips support multiple wireless
technologies and latest security standards, perfectly addressing
requirements for smart industrial, medical, and consumer
devices
Geneva, Switzerland, March 5, 2024 – STMicroelectronics
(NYSE: STM), a global semiconductor leader serving
customers across the spectrum of electronics applications, has
revealed the next generation of its short-range wireless
microcontrollers. These innovative, all-in-one components enable
wearables and smart objects including smart home devices, health
monitors, and smart appliances to become ever more miniaturized,
easy to use, secure and affordable.
Short-range wireless technologies like Bluetooth® LE, Zigbee®
and Thread (popular in smart meters and smart buildings) are the
fabric connecting smart devices to home bridges, gateways, and
controllers including smartphones. As we all seek solutions for
making life more economical, sustainable, and comfortable, vendors
are looking to bring creative and high-performing new solutions to
market more quickly, within tight cost constraints. They need to be
stylish, too: tiny, low-profile, or even embedded out of sight in
other equipment, such as in smart bulbs. Going wireless is a part
of this trend, for freedom, flexibility, and fashion.
Wireless microcontrollers like ST’s new STM32WBA5 product line
allow a one-chip solution that’s extremely compact, reduces the
bill of materials, and shortens the time to market by relieving
wireless design challenges. Also, being compatible with the
development tools and software packs of the STM32 microcontroller
development ecosystem, the new line simplifies migrating existing
products designed for wired connections.
The new series’ flagship STM32WBA55 microcontroller can
communicate using multiple wireless standards concurrently,
including low-energy Bluetooth LE 5.4, Zigbee, Thread, and Matter
(Thread RCP). Matter border router is a perfect match with the
STM32WBA5 for this new open-source connectivity standard for
smart-home and IoT (Internet of Things) devices. In this way, the
STM32WBA55 supports a great user experience while simplifying
hardware and software engineers’ development journey, aiding
affordability and time to market for the new product.
With this new generation, ST has also introduced support for the
recently completed Bluetooth LE Audio specifications that enable
exciting and innovative new products for richer listening and
hearing experiences. These include the new Bluetooth Auracast™
feature, which opens the door to a new world of audio broadcasting
applications.
“Lead customers are already appreciating the enhanced wireless
performance, flexibility, and security of our latest STM32WBA
wireless microcontrollers. They are creating diverse products
including smart thermostats, tracking devices, smart chargers,
headsets, power tools, and smart meters,” said Benoit Rodrigues,
Wireless MCU Division General Manager, STMicroelectronics. “The
extensive software ecosystem that provides communication stacks,
microcontroller-specific software packs, sample code, and tools
helps developers bring new products to market based on these MCUs
quickly and efficiently.”
The STM32WBA series is the first wireless MCU in the market to
achieve the important SESIP (Security Evaluation Standard for IoT
Platforms) Level 3 security certification. With this, smart devices
containing STM32WBA microcontrollers are ready to satisfy the US
Cyber Trust Mark and EU Radio Equipment Directive (RED) regulations
due to become mandatory in 2025.
“We work with smart asset tracking devices which are connected
through Bluetooth to mobiles and through mobile apps to the cloud,
enabling us to deliver complete asset tracking management for our
customers. ST’s microcontrollers bring wireless connectivity to our
multi-mode trackers,” said Olivier Hersent, CEO, Abeeway (Actility
Group). “We have selected the new wireless connectivity product,
STM32WBA5, for its enhanced performance with ultra-low power radio
capabilities, which is key for our battery powered devices. They
ensure stable connectivity in the harsh industrial environment
where we operate, combined with security that meets the highest
industry standards.”
“We believe that gaming peripherals should be as unique and
accessible as the gaming community itself,” said Tom Roberts, CTO,
Performance Designed Products (PDP). “ST and PDP have worked
together through several Video Game generations, and we have used
STM8 and STM32 devices for many years. ST products consistently
provide the features we need in our highly competitive market
segment. We recently selected ST’s short-range wireless
connectivity product, the STM32WBA5, based on the integrated MCU
and Bluetooth low-energy technology, as the right solution for a
new, groundbreaking game controller. The STM32WBA offered us an
ideal combination of performance, peripherals, cost efficiency and
ecosystem support that enabled simple and fast development.”
The new STM32WBA5 product line will be available on st.com on
March 12. Sample requests and pricing information are available
from local ST sales offices. ST will introduce a ready-to-use
module containing the STM32WBA, integrated with necessary external
components including power-supply and antenna-balancing circuitry,
in June 2024.
Technical Notes to Editors:The new wireless
microcontrollers (MCUs) introduced today, the STM32WBA54 and
STM32WBA55, contain a 100MHz Arm® Cortex®-M33 core that brings
latest-generation performance and Arm TrustZone architecture
isolating secure processes and storage. With up to 1MB of Flash
memory, they provide generous code and data storage. They also have
inherently low power consumption, incorporating background
autonomous mode, flexible power-saving states, and analog and
digital peripherals proven in ST’s STM32U5 ultra-low-power
MCUs.
ST’s latest 2.4GHz radio, integrated alongside the MCU, is the
first to let the application control the RF output power. The
adjustment range allows up to +10dB to ensure reliable wireless
connections even in difficult operating conditions.
The new wireless MCUs also support the latest Zigbee standards
including Release 22 and Release 23, which significantly extends
the Zigbee core stack for greater security, reliability, and
usability.
By supporting LE Audio, designed for the Bluetooth Low Energy
radio, the STM32WBA series enhances flexibility to optimize audio
quality and power consumption. Moreover, the latest use cases
coming with LE Audio expand opportunities to create imaginative new
products leveraging capabilities such as broadcast and multicast
audio.
The new MCUs are fully supported in the STM32 ecosystem, with
dedicated software packages and tools for configuring the hardware
and testing the wireless performance, as well as evaluation kits
and rich online support. These include wireless protocol stacks and
code examples, prototype boards and expansion cards, a developer’s
wiki, and more online including ST’s STM32 github repository and
the STM32 developer community.
