NXP MCX A34 mixed-signal Cortex-M33 MCU delivers 17x faster math acceleration for motor control and HVAC systems

NXP has launched the MCX A34 mixed-signal Arm Cortex-M33 industrial MCU, an upgrade of the MCX A14x and MCX A15x MCUs, which were introduced in 2024. While the A14x/A15x offered Cortex-M33 cores up to 96 MHz, 128 KB Flash, 32 KB SRAM, a 12-bit ADC, the A34 scales up with a 180 MHz core, up to 1 MB Flash, 256 KB SRAM, four 16-bit ADCs (3.2 Msps), four OpAmps, a 12-bit DAC, and FlexPWM with enhanced quadrature decoding. It also features a dedicated Math Acceleration Unit (MAU) that executes trigonometric, reciprocal, and square root operations up to 17x faster than CMSIS-DSP, a SmartDMA coprocessor for offloading data transfers, and advanced security features with tamper detection and secure boot. Connectivity is also richer, with up to six UARTs, four I²C, two SPI, and a CAN FD interface. MCX A34 specifications: MCU core – Arm Cortex-M33 core clocked at up to 180 […]

NXP MCX W72x Cortex-M33 wireless SoC supports Bluetooth 6.0 with Channel Sounding, Zigbee, Thread and Matter

NXP MCX W72x series Cortex-M33 wireless SoCs support for Bluetooth 6.0 and an 802.15.4 radio for Zigbee, Thread, and Matter. The MCX W72x family also implements Bluetooth Channel Sounding for accurate distance measurements with the help of a Localization Compute Engine (LCE) to reduce latency. It’s the second MCU part of the MCX W wireless family following the MCX W71x MCU, and the new MCX W72x wireless microcontroller is offered with up to 264 KB SRAM, 2MB flash, features a dedicated Cortex-M33 core to handle Bluetooth and 802.15.4 radios, implements an EdgeLock Secure Enclave for security, and integrates plenty a range of I/Os in a 48-pin package. NXP MCX W72x key features and specifications: MCU cores and memory/storage Application core – Arm Cortex-M33 core up to 96 MHz with 2 MB program Flash with ECC, 264 kB SRAM with ECC and parity Networking core – Arm Cortex-M33 core with dedicated […]

NXP MCX L14x and MCX L25x ultra-low-power Cortex-M33 MCUs target energy harvesting and battery-powered devices

NXP Semiconductors has launched the MCX L series of ultra-low-power Arm Cortex-M33 MCUs with the MCX L14x and MCX L25x SKUs. The new series offers similar peripherals as the rest of the MCX portfolio but uses a new “power management architecture that supports always-on, battery-powered applications” The MCX L series uses a dual domain architecture, with “real-time processing and ultra-low-power sensing functions in a single device.” The Arm Cortex-M33 core supports real-time processing functions while the Arm Cortex-M0+ core offers always-on operation in the ultra-low-power sense domain. The new microcontrollers reportedly use three times less power than their predecessors. The ultra-low-power series is targeted at energy-constrained applications, powered by a battery, ultracapacitor, or power harvesting circuit. These include building control, industrial sensing, smoke and fire alarms, flow meters, smart appliances, and motion detectors. NXP MCX L14x and L25x specifications: CPU Main core: Arm Cortex-M33 microcontroller @ up to 96 MHz […]

Arduino Core for Zephyr beta released – Let’s give it a try!

Last July, Arduino announced plans to switch from the soon-to-be deprecated Arm Mbed to Zephyr RTOS, and the company has now outed the first beta release of “Arduino Core for Zephyr OS” for a range of boards. From the user’s perspective, this should not change anything. However, there are massive changes under the hood and Arduino sketches are built and executed differently with the Arduino Core for Zephyr. Some highlights of the new Zephyr-based Arduino core implementation include: Dynamic sketch loading – Sketches are compiled as ELF files and dynamically loaded by a precompiled Zephyr-based firmware. Zephyr subsystems support threading, inter-process communication, and real-time scheduling. Fast compiling and smaller binaries since a thin layer of user code and libraries are compiled, while the rest of the ZephyrOS is already binary. You can get started straightaway with the code and instructions on GitHub. You’ll need Arduino 2.x.x for this to work. […]

NXP launches MCX A14x and MCX A15x Arm Cortex-M33 MCUs along with FRDM-MCXA153 development board

NXP has just announced the launch of the MCX A series Arm Cortex-M33 microcontrollers with the MCX A14x running up to 48 MHz and the MCX A15x running up to 96 MHz. The devices support up to 128KB flash and 32KB SRAM, offer I2C, I3C, and SPI sensor interfaces, and integrate support for BLDC/PMSM motor control. NXP first unveiled the NXP MCX general-purpose Arm MCU family with 30 times faster machine learning at Embedded World 2022, but at the time we had limited information although four series were planned with the MCX N Advanced series up to 250 MHz, the MCX A essential series up to 96 MHz, the MCX W Wireless series with Bluetooth LE, and the MCX L Low-power series. The MCX A series has just been launched, and the high-end MCX N also has its own product page with the N94x and N54x variants. We’ll focus on […]

NXP unveils MCX general-purpose Arm MCU family with 30x faster machine learning performance

NXP has announced a new MCX general-purpose Arm Cortex-M MCU family designed for advanced industrial and IoT edge computing and integrating an NXP neural processing unit (NPU) capable of delivering over 30 times higher performance than running the AI inference tasks on an Arm Cortex-M33 core alone. The new MCX portfolio builds upon the earlier NXP LPC and Kinetis microcontroller families, but does not replace these, and aims to improve machine learning performance and security for a variety of applications including machine learning, wireless, voice, motor control, analog, and more. The new MCX family will be available in four series: MCX N Advanced series Designed for secure, intelligent applications 150 MHz to 250 MHz Neural processing unit (NPU) and DSP for real-time inference EdgeLock Secure Subsystem MCX A Essential series Optimized to provide critical functionality for applications such as motor control 48 MHz to 96 MHz Built-in timers, low pin […]
