Tiny certified sub-GHz module enables proprietary networks for enhanced security

Microchip has launched the industry’s smallest IEEE 802.15.4-compliant module, which measures 12.7 x 11 mm and combines an ultra-low-power MCU with a sub-GHz radio.

Based on IEEE 802.15.4, the SAM R30 module allows proprietary networks that can be easily customised and configured. This is ideal for applications where interoperability is not desired due to their inherent vulnerability to remote attacks. IEEE 802.15.4-based network devices can sleep for extended periods of time and still remain part of the network. The SAM R30 module features ultra-low-power sleep modes, with wake from GPIO or its built-in RTC while consuming approximately 800 nA.

The SAM R30 module eliminates the need for a separate MCU in the design. The device also offers up to 256 KByte Flash and 40 KByte RAM, as well as serial data interfaces, USB, and digital and analogue I/O for advanced sensor development.
Due to its operation in the sub-GHz RF spectrum, the SAM R30 module offers double the connectivity range and better penetration of walls and floors than similarly powered devices using the 2.4 GHz frequency band. The SAM R30 module is certified with the FCC, Industry Canada (IC) and Radio Equipment Directive (RED), reducing time to market and RF testing certification costs. Microchip also provides the free MiWi protocol stack to allow the easy implementation of proprietary point-to-point, star or self-healing mesh networks.

Developers can select a single-chip 32- or 48-pin SAM R30 System-in-Package (SiP) for flexible design layout or the certified SAM R30 module for fastest time to market.

To help development, the ATSAMR30M-XPRO Extension Development Board is supported by the Atmel ICE Debugger/Programmer (ATMEL-ICE) and the Atmel Studio 7 IDE with demo code examples supporting each network configuration.
