NXP Semiconductors has launched the MCX W sequence of scalable wi-fi microcontrollers which declare to function {industry}’s first wi-fi MCU with Bluetooth channel sounding, and add multiprotocol, software program upgradeable connectivity to its MCX portfolio to allow future flexibility for industrial and IoT units.
The brand new MCX W sequence allow edge units with safe wi-fi MCUs for Matter, Thread, Zigbee, and Bluetooth Low Power. The MCX W sequence builds on the corporate’s FRDM growth platform, in addition to the MCX portfolio system structure, core, peripherals, and MCUXpresso developer expertise to allow a scalable MCU platform that makes it simpler to rapidly create new merchandise or goal new use circumstances throughout the economic and IoT markets.
The primary two households within the MCX W sequence, the MCX W71x and W72x, assist maximize flexibility over time for good linked units with a software-upgradeable unbiased radio subsystem. This subsystem permits multitasking by offloading the principle core, liberating it to run the first utility. Supported by scalable reminiscence sizes for the applying and connectivity stacks, in addition to over-the-air (OTA) updates, the MCX W sequence permits safe linked edge units to be upgraded over time as client wants change and connectivity protocols like Matter proceed to evolve.
NXP mentioned in its announcement that the brand new sequence consists of the {industry}’s first wi-fi MCU to help the brand new Bluetooth channel sounding commonplace, which improves the accuracy and safety of distance measurement in comparison with conventional Bluetooth know-how for a variety of functions, reminiscent of safe entry, asset monitoring and indoor wayfinding. Complementing its NXP’s Trimension portfolio of ultra-wideband (UWB) safe radar and effective ranging merchandise, the MCX W will assist evolve ambient computing right into a ‘broad vary of market segments and functions’’, the corporate mentioned.
With connectivity requirements persevering with to evolve over time, software program upgradeability will turn into important to maintain units within the area longer, cut back redesigns and ship differentiated options. The power to handle future adjustments to requirements and altering efficiency and reminiscence wants through OTA (over-the-air) firmware updates is a key function. This helps builders help a number of connectivity requirements, whereas scalability throughout the complete MCX portfolio makes it simpler to develop a wide range of finish units based mostly on a typical platform, lowering growth prices and complexity.
Charles Dachs, senior vice chairman and basic supervisor, industrial and IoT, for NXP, mentioned, “The way forward for good linked units is evolving sooner than ever earlier than, with new options and capabilities launched recurrently. The MCX W sequence enriches the general MCX portfolio, making it simpler for builders to convey superior connectivity to their designs and enabling new improvements to be deployed to the subsequent era of IoT and industrial units.”
The MCX W sequence help each standalone or hosted architectures and are pin- and software-compatible, permitting builders to simply migrate to the half that most closely fits their use case. The MCX W71x and W72x households function a 96 MHz Arm Cortex-M33 core. Each households leverage an unbiased radio subsystem, with a devoted core that offloads the principle CPU, preserving it for the first utility, and extra reminiscence to help software program updates. Additionally they provide superior safety with an built-in NXP EdgeLock safe enclave core profile.
The brand new MCU sequence affords a large working temperature vary from -40°C to 125°C and peripherals for industrial functions, together with a CAN interface and are a part of NXP’s 15-year product longevity program to help long-term industrial use.

The MCX W71x household helps easier IoT units with a single chip resolution or performing as a co-processor in a hosted structure. An entire software program resolution permits the MCX W71x to function seamlessly as a community or radio co-processor with NXP’s broad portfolio of MCX MCUs, i.MX RT crossover MCUs, and that i.MX functions processors.
The MCX W72x household provides Bluetooth channel sounding capabilities, with a devoted on-chip localization compute engine accelerator to cut back ranging latency. It incorporates extra reminiscence to help application-specific code, connectivity stacks, and over-the-air firmware updates. As well as, the radio subsystem can run the complete Thread or Zigbee stack alongside the Bluetooth Low Power stack. This implies extra dependable wi-fi efficiency, because the real-time actions of the radio run on a separate core from the applying.
Safety can also be addressed and the MCX W sequence has options that can assist builders to handle compliance with upcoming cyber safety laws such because the U.S. Cyber Belief Mark and European Cyber Resilience Act and different safety requirements, reminiscent of IEC 62443, using its built-in EdgeLock safe enclave (core profile) that protects delicate safety capabilities and natively helps EdgeLock 2GO providers. It additionally consists of system authentication, safe boot, and safe firmware set up and replace. It accelerates connectivity requirements’ cryptography with safe key set up and administration in untrusted manufacturing websites.
NXP added that since it’s the solely silicon vendor accredited by the CSA to challenge Matter safety certificates as a Product Attestation Authority to different firms, the MCX W simplifies and accelerates Matter finish system productization and manufacturing with a an end-to-end resolution for securely provisioning IoT units.
Developer enablement
NXP’s FRDM boards allow a low-cost, scalable {hardware} growth platform supported by the MCUXpresso developer expertise throughout the complete MCX portfolio. MCX FRDM boards embrace industry-standard headers, quick access to the MCU’s I/Os, and an on-board MCU-Hyperlink debug probe. The MCX W FRDM boards embrace full wi-fi certification, offering builders with a robust place to begin for their very own designs.
The MCUXpresso ecosystem, together with the MCUXpresso SDK, gives production-grade software program, drivers and middleware multi function central location. NXP gives validated and licensed stacks for a variety of IoT connectivity requirements, reminiscent of Matter, Thread, Zigbee, and Bluetooth Low Power, to streamline the event and deployment of IoT units.
The MCX W sequence will start sampling in 2H 2024.
