Key Features
- Integrated ARM Cortex-M0 core at 48 MHz with sub-GHz 802.15.4 transceiver eliminates external radio chip
- 256 KB flash and 32 KB RAM support complex wireless mesh stacks such as MiWi and Thread
- VQFN-32 package with ADC and DMA enables single-chip IoT sensor node design at under 32 pins
Applications
ATSAMR30E18A-MU is designed for low-power wireless sensor networks and smart metering applications requiring a sub-GHz radio and an ARM Cortex-M0 processor in a single chip. Its 802.15.4 PHY supports mesh topologies used in industrial automation, building automation, and agricultural IoT where long-range, interference-resistant communication is preferred over 2.4 GHz. The VQFN-32 form factor minimizes BOM and PCB area for battery-operated remote nodes that must operate for years on a coin cell.

Frequently Asked Questions
What wireless standard does ATSAMR30E18A-MU support and at what frequency band?
ATSAMR30E18A-MU integrates an IEEE 802.15.4 compliant sub-GHz radio transceiver operating in the 700 MHz to 950 MHz ISM bands depending on regional variant, offering superior range and wall-penetration compared to 2.4 GHz radios at equivalent transmit power levels.
How much flash and RAM does ATSAMR30E18A-MU provide for running a wireless mesh stack?
ATSAMR30E18A-MU includes 256 KB of flash program memory and 32 KB of SRAM, which is sufficient to run Microchip's MiWi or a lightweight Thread stack alongside a sensor application, leaving headroom for over-the-air firmware update buffers at 48 MHz processor speed.
Can ATSAMR30E18A-MU replace a discrete MCU plus radio module combination in a compact sensor node?
Yes. ATSAMR30E18A-MU combines a 48 MHz ARM Cortex-M0 processor, 256 KB flash, sub-GHz 802.15.4 radio, ADC, and DMA in a single VQFN-32 package, replacing at least 2 ICs and reducing BOM cost and board space by roughly 50% compared to a separate MCU and radio module solution.
