Charbax | NXP MCX W wireless Bluetooth channel sounding microcontrollers, Zigbee at Embedded World 2024 #ew24 @charbax | Uploaded April 2024 | Updated October 2024, 1 week ago.
Director of Marketing in Wireless Connectivity at NXP, presents the new MCX W series of wireless microcontrollers at Embedded World 2024. These microcontrollers support Bluetooth Low Energy (BLE) and IEEE 802.15.4, enabling technologies like Thread and Zigbee. The demo showcases the MCX W72's ability to measure distances between two objects using Bluetooth Low Energy with channel sounding.
The demonstration involves an MCX W72-based board acting as a mobile phone and another board simulating a thermostat. This setup illustrates how Bluetooth channel sounding facilitates distance measurement, enabling location-based control of devices like air conditioning. As the mobile phone board moves away from the thermostat, the system automatically turns off the AC to save energy, then turns it back on when the mobile phone board gets closer.
Bluetooth channel sounding is a new feature under development. It uses time-of-flight technology instead of the older Received Signal Strength Indicator (RSSI) method, providing higher accuracy and enhanced security against potential attacks. This technology can measure distances with an accuracy of plus or minus half a meter, allowing for more precise and secure applications.
Despite its accuracy, the technology has limitations. It requires line-of-sight between devices and may not work well if obstacles or walls block the signal. However, minor obstructions like furniture or other devices may not pose significant issues. While Bluetooth channel sounding technology is still in its early stages, its potential applications in energy savings and smart homes are promising.
The demo also introduces a new wireless technology called Matter, which promotes interoperability in smart homes. NXP showcases a full Matter system with a Matter controller managing the interface, a Thread border router, and other components. The MCX W71, another member of the MCX W series, serves as a temperature sensor in this setup, demonstrating its use in real-world applications.
The Matter demo also includes other devices like a contact sensor, which interacts with the MCX W71. The contact sensor can trigger other smart home functions, such as controlling lights or window shades, depending on whether a door is open or closed. This versatility highlights the low-power, multi-protocol capabilities of the MCX W series, supporting both Bluetooth Low Energy and Thread/Zigbee on a single chip.
The MCX W71 is expected to be available for sampling in the second half of 2024. Its 2.4 GHz radio allows for compatibility with Bluetooth Low Energy and other wireless protocols like Thread and Zigbee, ensuring flexibility in smart home applications. While it does not support higher or lower frequency ranges, its versatility in the existing 2.4 GHz spectrum makes it a valuable addition to the smart home ecosystem.
NXP also introduces a different technology under the MCX series, known as the MCX N. This microcontroller does not feature wireless connectivity but comes with an integrated Neutron neural processing unit. The demo shows its ability to detect presence and interact with users through touch or gesture-based controls, opening new possibilities for user interfaces and smart home automation.
The MCX N's demo reveals how users can control settings by pressing or waving their hand over the sensor. This interaction changes settings like temperature, demonstrating how neural processing can enhance smart devices' capabilities. This technology could lead to innovative applications in smart home environments, providing touchless control and more intuitive user experiences.
Overall, the new MCX W and MCX N series from NXP offer a wide range of capabilities for wireless connectivity and neural processing. With Bluetooth Low Energy channel sounding, Matter integration, and advanced user interaction technologies, these microcontrollers are poised to play a significant role in the future of smart home and energy-efficient applications. As these products move towards full release, the industry anticipates further developments and innovative uses for these advanced microcontrollers.
