SiP bundles Microchip/Atmel MCU plus sub-GHz wireless transceiver
Microchip’s SAM R30 System in Package (SiP) is a single-chip RF microcontroller (MCU) that incorporates an ultra-low power ARM microcontroller (from Microchip’s Atmel acquisition) with an 802.15.4 sub-GHz radio to provide multi-year battery life in a 5 mm package.

This provides, Microchip says, design flexibility and reliability in a single, small package, suiting it for connected home, smart city and industrial applications. It simplifies point-to-point, star or mesh networking in the 769-935 MHz range, using Microchip’s free MiWi point-to-point/star network protocol stack for fast designs.


Aimed at battery-powered wirelessly connected systems, the low-power SAM R30 promises battery life of multiple years. The SiP is built using the SAM L21 MCU which uses the energy efficient ARM Cortex M0+ architecture. The SAM R30 features ultra-low power sleep modes, with wake from serial communication or General-Purpose Input/Output (GPIO) while consuming 500 nA.


With the ability to operate within the 769-935 MHz range, the SAM R30 SiP gives developers the flexibility to implement a point-to-point, star or mesh network. Mesh networking capabilities will be available later in 2017. Nodes outfitted with the SiP can be positioned as far as 1 km apart, with the ability to double the range in a star topology. 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.


Developers can begin prototyping immediately with the ATSAMR30-XPRO development board, priced at $65. This USB-interfaced development board is supported by the Atmel Studio 7 Software Development Kit (SDK). The SAM R30 SiP is available in two QFN packages; ATSAMR30E18 in a 32QFN package, or ATSAMR30G18 in a 48QFN package.
