Microchip’s SAM R30 module provides multiple years of battery life
Designers of wireless, space-constrained sensor nodes require connectivity solutions that minimise size and provide multiple years of battery life.

Microchip Technology announced the industry’s smallest IEEE 802.15.4-compliant module that combines an ultra-low-power microcontroller (MCU) with a sub-GHz radio, accelerating time to market and providing long-lasting battery life in wireless-networked sensors. At half the size of the next smallest module on the market, the SAM R30 module meets the needs of space-conscious designs such as home automation sensors and controls.

Based on IEEE 802.15.4, the SAM R30 module supports 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, such as alarm systems, building automation, smart cities and industrial sensor networks. 

A key advantage of an IEEE 802.15.4-based network is that member devices can sleep for extended periods of time and remain part of the network. The SAM R30 module features ultra-low-power sleep modes, with wake from General-Purpose Input/Output (GPIO) or its built-in Real-Time Clock (RTC) while consuming approximately 800 nA. Devices can sleep for years, only waking as needed to transmit data.

Developers can begin prototyping with the ATSAMR30M-XPRO Extension Development Board, supported by the Atmel ICE Debugger/Programmer (ATMEL-ICE) and the easy-to-use Atmel Studio 7 Integrated Development Environment with demo code examples supporting each network configuration.
