NXP Launches New MCX Portfolio of Microcontrollers


The MCX Microcontrollers are available in four different series, with high-speed, wireless connectivity, low power and small pin count versions


NXP Semiconductors have launched the new MCX range of microcontrollers, designed to advance innovation in smart homes, smart factories, smart cities and across many emerging industrial and IoT edge applications. The range includes four series of devices built on a common platform and is supported by the MCUXpresso suite of development tools, for programming and software development. This combined offering allows developers to maximize software reuse across the portfolio to help speed application development. The range also features the first instantiation of NXP's new, specialized neural processing unit (NPU) for accelerating inference at the edge, delivering up to 30x faster machine learning throughput compared to a CPU core alone.

Click for Larger Image - NXP Launches New MCX Portfolio of Microcontrollers Driven by the proliferation of edge devices, the microcontroller has evolved dramatically over the last few decades. While they are at the heart of many of today's edge applications, the next generation of intelligent applications will require a new class of MCUs that allow developers to navigate a complex landscape of power, performance and security requirements, together with connectivity options, while balancing total system cost and energy efficiency. The MCX series is built on a common foundation of core technologies and supported by a unified software suite for maximal software reuse, enabling the flexibility needed to address this challenge. The breadth of the MCX portfolio allows developers to select devices that best fit their application needs, freeing them to invest in differentiating aspects of their design.

The four series in the MCX portfolio are designed for ease of use, to simplify migration and to scale up or down as needed. The portfolio is based on high-performance Arm Cortex-M cores and integrates a comprehensive set of peripherals for design flexibility. MCX devices feature up to 4 MB of on-chip flash memory, low power cache and advanced memory management controllers, plus up to 1MB of on-chip SRAM to further enhance real-time performance of edge applications.

“As we approach the milestone of 75 billion connected devices, we are entering a new era of edge computing, requiring us to fundamentally rethink how to best architect a flexible MCU portfolio that is scalable, optimized and can be the foundation for energy efficient industrial and IoT edge applications today and in the decades to come. By building on our strong legacy in MCUs, this new portfolio will offer the performance and integration needed to address the real-time workloads for the next wave of innovation.” Ron Martino, Executive Vice President and General Manager of Edge Processing at NXP.

Machine learning and run-time inference will be available with NXP's eIQ® ML software development environment. Developers can utilize the easy-to-use tools offered with the eIQ software, to train ML models targeting either the NPU or the CPU core and deploy them on the MCU. MCX families that are built following NXP's security-by-design approach will offer secure boot with an immutable root-of-trust, hardware accelerated cryptography and, on select families, a built-in EdgeLock® secure subsystem.
