Low-power MCU integrates sub-GHz radio

The SAM R30 system-in-package from Microchip meets the power-conscious needs of battery-powered wirelessly connected systems, including connected home, smart city, and industrial applications. This single-chip RF microcontroller integrates an 802.15.4 sub-GHz radio, providing multi-year battery life in a compact 5×5 mm package.

Based on an energy-efficient 32-bit ARM Cortex-M0+ architecture, the SAM R30 offers ultra-low-power sleep modes with wake from GPIO, serial communication, or real-time counter. The part typically draws less than 500 nA from a 1.8 V battery supply.
