Microchip Technology Inc. has recently introduced the SAM R30 System in Package (SiP) that incorporates a single-chip ultra-low power RF microcontroller along with an 802.15.4 sub-GHz radio. It’s a compact 5 mm package with a multi-year battery life, design flexibility, and proven reliability. This makes it ideal for connected home, smart city, and other industrial applications.
In the present situation, when demand for battery-powered wireless systems is huge, the Sam R30 package meets the power-conscious demands of the market by offering extended battery life. The SiP is built using the SAM L21 MCU leveraging the Cortex® M0+ architecture, the most energy-efficient ARM®-based architecture available. More features include ultra-low power sleep modes, with wake from serial communication or General-Purpose Input/Output (GPIO) while consuming a mere 500 nA.
The SAM R30 SiP can operate within the 769-935 MHz range and hence gives developers the flexibility to implement a point-to-point, star or mesh network. Microchip helps developers get started immediately with Microchip’s free MiWi™ point-to-point/star network protocol stack. Mesh networking capabilities will be available later this year.

With the ability to double the range in a star topology, nodes outfitted with the SiP can be positioned as far as one kilometer apart. As far as a mesh network is concerned, the SAM R30 delivers reliable wide-area coverage for applications like street lighting or wind and solar farms.
“This SAM R30 SiP offers an excellent migration path from a discrete MCU and radio to a single-chip solution for more compact, cost-effective designs,” said, Steve Caldwell, Vice President of Microchip’s wireless solutions group. “The combination of our industry-proven connectivity technology with the high performance of the SAM L21 MCU creates a reliable, extremely low-power solution.”
Pricing and Availability
The SAM R30 SiP is available in two QFN packages to be sampled or purchased in volume production quantities as specified below:
• The ATSAMR30E18 in a QFN32 package is available for $4.11 each in 10k unit quantities.
• The ATSAMR30G18 in a QFN48 package is available for $4.26 each in 10k unit quantities.
• The ATSAMR30-XPRO development board is available for $65 per board.
