February 26, 2019 – Microchip Technology announced an IEEE 802.15.4-compliant module that combines a microcontroller (MCU) with a sub-GHz radio. The SAM R30 module is designed to meet the needs of space-conscious needs such as home automation sensors and controls.
Based on IEEE 802.15.4, the SAM R30 module supports proprietary networks that can be customized and configured. This is suitable 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 feature 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 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.
The SAM R30 module measures 12.7 x 11 mm and includes the necessary features to drive any remote connected sensor, thereby eliminating the need for a separate MCU in the design. The device also offers up to 256 kilobytes (KB) of Flash and 40 KB of RAM, as well as serial data interfaces, USB, and digital and analog I/O for sensor development.
The SAM R30 module is certified with the Federal Communications Commission (FCC), Industry Canada (IC) and Radio Equipment Directive (RED).
