Product details
Overview
ATSAMR30G18A-MUT from Microchip Technology is an IEEE 802.15.4-2011-compliant sub-GHz System-in-Package (SiP) integrating an ARM Cortex-M0+ MCU (48 MHz, 256 KB Flash, 32 KB SRAM) and AT86RF212B transceiver. It operates across 779–787 MHz (China), 863–870 MHz (Europe), and 902–928 MHz (North America), delivering +11 dBm TX output and –110 dBm RX sensitivity for low-power wireless sensor networks.
For engineers reviewing the ATSAMR30G18A-MUT datasheet, ATSAMR30G18A-MUT pinout, ATSAMR30G18A-MUT application, or ATSAMR30G18A-MUT equivalent, this SiP enables rapid development of battery-powered IoT endpoints requiring integrated RF, hardware-accelerated MAC, AES-128 security, and SleepWalking peripherals with <1.4 μA standby current.
Technical Context
The ATSAMR30G18A-MUT combines a SAM L21-based Cortex-M0+ microcontroller and AT86RF212B transceiver in a single 48-pin QFN package, with internal SPI interconnect between MCU and RF die. Its RF subsystem supports BPSK (20/40 kbps) and O-QPSK (100–1000 kbps) modulation, hardware CSMA-CA, auto-acknowledge, and FCS computation per IEEE 802.15.4-2011.
Power management includes domain gating, SleepWalking peripherals, and ultra-low-power modes: active mode down to 60 μA/MHz, standby down to 1.4 μA, and transceiver RX_ON at 9.4 mA. The device integrates a 12-bit 350 kSPS ADC, 48-channel PTC, USB 2.0 FS, five SERCOMs, and three TCC timers with dead-time control and dithering.

Pinout & Package
ATSAMR30G18A-MUT uses a 48-pin QFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad connected to GND. Pin functions are multiplexed across PORT A/B/C, supporting up to 28 GPIOs, SERCOM, TCC, TC, USB, ADC, PTC, and RF control signals (SLP_TR, IRQ, /SEL, MOSI/MISO/SCLK).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar sub-GHz wireless microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATSAMR30E18A-MUT | 32-pin QFN, 16 GPIOs, no XOSC32K, reduced PTC (6×2), 4 ADC channels vs. 8; identical core, Flash, SRAM, and RF performance. | Targeted for space-constrained nodes where RF range and security match but I/O count and analog channel density are lower. | Select when board area is critical and peripheral count permits reduction-no software porting required due to identical register map and toolchain support. |
| CC1312R1F3RGZT | Texas Instruments SimpleLink™ Arm Cortex-M4F MCU + integrated sub-1 GHz RF; 352 KB Flash, 80 KB RAM, higher compute throughput but larger 48-pin QFN footprint (7×7 mm same, but different pinout). | Preferred for applications needing DSP-intensive tasks (e.g., FFT-based spectral analysis) alongside RF, with TI's proprietary Stack and BLE/Sub-1GHz dual-mode capability. | Choose when migrating from TI ecosystem or requiring higher processing headroom; requires PCB redesign due to non-pin-compatible layout and different power sequencing. |
Compared with ATSAMR30G18A-MUT, ATSAMR30E18A-MUT offers identical RF and security features in a smaller package with fewer I/Os, while CC1312R1F3RGZT provides greater computational capacity and dual-band flexibility at the cost of ecosystem lock-in and layout incompatibility.

FAQ
What is the operating voltage range for the ATSAMR30G18A-MUT?
The ATSAMR30G18A-MUT operates from 1.8 V to 3.6 V across its entire industrial temperature range (–40°C to +85°C). This wide supply range supports direct integration with common lithium-thionyl chloride (3.6 V) and alkaline (1.5 V × 2) battery configurations when used with appropriate regulators or LDOs, and ensures stable RF performance under varying battery discharge curves.
Does the ATSAMR30G18A-MUT include an integrated crystal oscillator for the RF transceiver?
Yes, the ATSAMR30G18A-MUT integrates a 16 MHz crystal oscillator (XOSCRF) dedicated to the AT86RF212B transceiver. An external 16 MHz crystal must be connected to XTAL1/XTAL2 pins (PA14/PA15) for RF clock generation; the MCU also supports separate 32.768 kHz and 48 MHz clock sources for system timing and USB synchronization.
How many hardware timer/counter peripherals does the ATSAMR30G18A-MUT provide?
The ATSAMR30G18A-MUT includes three 16-bit Timer/Counters (TC) and three Timer/Counters for Control (TCC). Each TCC supports up to four waveform outputs with dead-time insertion, dithering, and fault protection-enabling precise motor control, LED dimming, or PWM-based sensor excitation without CPU intervention.
Can the ATSAMR30G18A-MUT support both USB device and host functionality simultaneously?
Yes, the ATSAMR30G18A-MUT's USB 2.0 Full-Speed interface supports embedded host and device modes concurrently. It implements eight endpoints and full USB descriptor handling in hardware, allowing it to act as a USB device (e.g., CDC virtual COM port) while simultaneously enumerating as a USB host to connect HID peripherals or flash storage-without external PHY or hub ICs.
What is the maximum number of capacitive touch channels supported by the ATSAMR30G18A-MUT?
The ATSAMR30G18A-MUT supports up to 48-channel capacitive touch sensing via its Peripheral Touch Controller (PTC), configured as an 8×6 matrix (X[7:0], Y[5:0]). This enables implementation of multi-button panels, linear sliders, rotary encoders, and proximity wake-up interfaces-all processed autonomously in low-power mode with hardware noise rejection.
