Low-Power Microcontrollers

Our low-power Arm® Cortex®-M4 with FPU microcontrollers help you build intelligent IoT devices with maximum battery life. Low-power microcontrollers are ideal for applications such as wearable fitness, medical, wireless sensor nodes, process automation, battery-powered sensors, and agriculture and livestock monitors.

  • Long battery life: Lowest retention mode power (maintain 512KB for 3.4µW) and active mode power (130µW/MHz, or 30µW/MHz running in PMU mode)
  • Intelligent: Largest memories (2MB flash) and code expansion through SPI execute-in-place peripheral let your application scale to any complexity needed
  • Secure: Options for advanced cryptographic support
