Ultra-Low-Power 32-Bit Microcontrollers (MCUs)

Our ultra-low-power, 32-bit Arm® Cortex®-M4 with FPU-based microcontrollers are built to run any application you can imagine—in places where you wouldn’t dream of sending other ultra-low-power MCUs. They’re as smart as they are power efficient, combining the biggest embedded memories of any MCUs in their class with our premier power technology. Now you can design smarter products without running out of code space or battery life. And with the most advanced cybersecurity ever, you’ll be ready for any threat you encounter.

Perfect for applications that require:

  • Crazy-long battery life: Lowest retention mode power (maintains 512KB for 3.5µW) and active mode power (as low as 45µW/MHz)
  • Near infinite code space: Largest memories (up to 3MB flash)
  • Ninja-like security: Options that support cryptographic algorithms
