Microchip Technology SAM R30 Ultra-Low Power RF Microcontrollers

Microchip Technology SAM R30 Ultra-Low Power RF Microcontrollers are a single-chip System in Package (SiP) incorporating an ultra-low-power MCU with an 802.15.4 sub-GHz radio. The SAM R30 MCUs deliver design flexibility and proven reliability all in a small 5mm x 5mm package, making it ideally suited for the connected home, smart city, and industrial applications. When used in a mesh network, the SAM R30 delivers reliable wide-area coverage for applications such as street lighting or wind and solar farms.

The Microchip Technology SAM R30 Ultra-Low Power RF MCUs, featuring Arm® Cortex® M0+ architecture, include ultra-low power sleep modes with wake from serial communication or General-Purpose Input/Output (GPIO) while consuming a mere 500nA. The SAM R30 SiPs are available in both a QFN-32 and QFN-48 package for design flexibility.
