Key Features
- Integrated 2.4 GHz IEEE 802.15.4 transceiver with -98 dBm sensitivity: enables long-range Zigbee, 6LoWPAN, and Thread mesh networking in a single module
- ARM Cortex-M0+ core at 48 MHz with 256 KB flash and 32 KB SRAM: provides sufficient compute resources for protocol stacks and application code without an external MCU
- Industrial temperature rating (-40°C to +85°C): ensures reliable wireless connectivity in harsh factory automation and outdoor IoT deployments
Applications
The ATSAMR21G18-MR210UAT is designed for IEEE 802.15.4-based wireless sensor networks including Zigbee and Thread home automation, smart metering, and industrial IoT nodes where its -98 dBm sensitivity enables reliable links across 100 m or more in typical indoor environments. Its self-contained SoC module form factor reduces RF design complexity, shortening time to market for building automation controllers, asset trackers, and wireless lighting control systems. The industrial temperature rating extends its use to outdoor monitoring nodes and factory floor deployments operating from -40°C to +85°C.

Frequently Asked Questions
What wireless standard and receive sensitivity does ATSAMR21G18-MR210UAT support?
The ATSAMR21G18-MR210UAT operates in the 2.4 GHz ISM band and complies with IEEE 802.15.4, achieving a receive sensitivity of -98 dBm, which is sufficient for robust Zigbee or Thread mesh links over distances exceeding 100 m in line-of-sight conditions.
What processor and memory resources are integrated in the ATSAMR21G18-MR210UAT SoC module?
The module integrates an ARM Cortex-M0+ processor running at up to 48 MHz, 256 KB of flash memory for program storage, and 32 KB of SRAM, providing enough headroom to run a Zigbee or Thread protocol stack alongside a lightweight application without an external microcontroller.
For a smart building wireless sensor deployment, how does the ATSAMR21G18-MR210UAT simplify the RF hardware design compared to a discrete transceiver approach?
A discrete IEEE 802.15.4 transceiver requires an external matching network, balun, crystal, decoupling capacitors, and an MCU, adding 10–15 components and demanding RF PCB layout expertise, whereas the ATSAMR21G18-MR210UAT integrates the 2.4 GHz radio, antenna, ARM Cortex-M0+ processor, 256 KB flash, and RF front-end into a certified module, reducing BOM count, eliminating regulatory re-testing, and cutting RF design time from weeks to days.
