MCX L14 Series Cortex®-M33 MCUs extends battery life for edge devices while delivering key features for industrial and commercial sensors. These devices combine an Arm® Cortex®-M33 core running up to 48 MHz with an autonomous sense domain powered by an Arm Cortex-M0+ core up to 10 MHz. This architecture enables low-power peripheral operation while the main core remains in Deep Power Mode, minimizing event-triggering power consumption and ensuring ultra-efficient data acquisition. The dual-domain design also provides physical separation of applications, simplifying development and certification of applications combining sensors, data processing and data transmission.

MCX L Series features EdgeLock® security capabilities for secure boot and hardware‑accelerated cryptography, meeting stringent requirements for wired and over-the-air (OTA) low-power transactions. Supported by MCUXpresso Developer Experience to optimize, simplify and accelerate embedded system development.

Features

Core Platform

  • Arm Cortex-M33 running up to 48 MHz and Arm Cortex-M0+ running up to 10 MHz

Memory

  • Up to 256 kB on-chip flash program memory with flash accelerator and 4 kB low-power cache
  • Minimum flash programming size: 16 bytes
  • Support Flash Swap with 8 kB granularity
  • Up to 64 KB static random-access memory (SRAM) and an additional 8 kB with ECC capability (supports one-bit correction and two-bit detection)
  • All RAM can be retained down to deep Power-down mode

Peripherals

  • Analog
    • Single‑ended 16‑bit analog-to-digital converter (ADC) with 2.1 MSamples/s rate in 16‑bit mode; supports 12‑bit mode at 2.5 MSamples/s for increased bandwidth
    • Integrated temperature sensor
    • Second 12‑bit ADC (500 kSamples/s) functional down to Deep Power‑down mode
    • One high‑speed comparator with eight input pins and an 8‑bit DAC as an internal reference, functional down to Deep Power‑down mode (can be used as a wake‑up source)
  • Timers
    • Three 32-bit standard general-purpose asynchronous timers/counters, each timer supports up to four capture inputs and four compare outputs; specific timer events can be selected to generate direct memory access (DMA) requests
    • Up to 2x quad timer (QTimer) cascadable with capture and compare capabilities (can be used for quadrature position encoder) that is functional down to Deep Power-down mode
    • Low-power timer (LPTimer)
    • Windowed Watchdog Timer
    • Micro‑Tick Timer running from a 1 MHz clock; wakes device from reduced‑power modes (down to Deep‑sleep with flash off) with extremely low power consumption
    • 42-bit free-running OS timer as continuous timebase for the system, available in any reduced power modes
  • Communication Interfaces
    • 2x Low-power serial peripheral interface (LPSPI) modules, supporting up to 50 MHz operation frequency in master mode
    • Up to 2x Low-power inter-integrated circuit (LPI2C) supporting Standard, Fast, Fast+ and Ultra Fast modes with one additional LPI2C is functional down to Deep Power-down mode
    • Up to 3x LPUART (Low Power UART), provides asynchronous, serial communication capabilities. 1 additional LPUART functional down to Deep Power-down mode

MCUXpresso Developer Experience

Security

  • Glitch attack resistant keyed access (Glikey)
  • Memory block controller (MBC) to Read, Write and Execute permission of each flash block where the configuration can be locked
  • Unique 128‑bit unique device serial number for identification (UUID)
  • Code watchdog for code‑flow integrity detection
  • Three‑level Readout Protection enabling different protection levels across system life‑cycle stages
  • Flash programming through in system programming (ISP) commands over LPUA+B28RT interface with auto baud

Packaging

  • 100 low-profile quad flat package (LQFP), 14x14mm and very thin fine-pitch ball grid array (VFBGA) 90, 6x6 mm
