Product details
Overview
ATSAMR30E18A-MUT from Microchip Technology is a 32-pin QFN IEEE 802.15.4 Sub-GHz System-in-Package microcontroller integrating an ARM Cortex-M0+ core (48 MHz), 256 KB Flash, 32 KB SRAM, and an AT86RF212B transceiver supporting 779–787 MHz (China), 863–870 MHz (Europe), and 902–928 MHz (North America). It delivers -110 dBm RX sensitivity and +11 dBm TX output power for low-power wireless sensor networks.
For engineers reviewing the ATSAMR30E18A-MUT datasheet, ATSAMR30E18A-MUT pinout, ATSAMR30E18A-MUT application, or ATSAMR30E18A-MUT equivalent, this page provides verified technical context, validated pin functions, confirmed RF performance metrics, and real-world deployment guidance for sub-GHz IoT edge nodes requiring integrated MAC/PHY hardware acceleration and ultra-low-power operation.
Technical Context
The ATSAMR30E18A-MUT combines a SAM L21 MCU die and AT86RF212B transceiver die in a single QFN32 package, with internal SPI interconnect (SERCOM4) and shared clock domains. Its RF subsystem supports BPSK (20/40 kb/s) and O-QPSK (100/250 kb/s per IEEE 802.15.4-2006/2011) plus proprietary high-data-rate modes including BPSK-40-ALT for FCC 15.247 compliance.
Hardware-assisted MAC features include Auto-Acknowledge, CSMA-CA with Listen-Before-Talk, automatic address filtering, FCS computation, RSSI measurement, and Clear Channel Assessment - all executed without CPU intervention. The 128-byte TX/RX frame buffer and integrated PLL enable fast frequency hopping and deterministic packet handling in battery-powered mesh endpoints.

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 |
|---|---|---|---|
| ATSAMR30G18A-MUT | 48-pin QFN, 28 GPIOs, 8 ADC channels, XOSC32K integrated, full PTC (8×6), additional SERCOM and TCC instance. | Required for designs needing >16 I/O, RTC calendar with 32.768 kHz crystal, or higher-channel capacitive touch. | Select when board layout allows larger package and application demands expanded analog or timing resources. |
| CC1352P1F3RGZR | Texas Instruments SimpleLink™ dual-band (Sub-GHz + 2.4 GHz), ARM Cortex-M4F, 352 KB Flash, integrated RF power amplifier (+20 dBm). | Supports concurrent Sub-GHz and BLE/Thread operation; requires separate antenna switching or diplexer for dual-band use. | Choose for hybrid protocols or where +20 dBm TX output is mandatory for non-line-of-sight outdoor coverage. |
Compared with ATSAMR30G18A-MUT, the ATSAMR30E18A-MUT trades I/O count and PTC capacity for smaller footprint and lower BOM cost; versus CC1352P1F3RGZR, it offers simpler RF integration and lower active power but lacks 2.4 GHz support and higher TX power.

FAQ
What is the maximum RF output power supported by the ATSAMR30E18A-MUT?
The ATSAMR30E18A-MUT supports up to +11 dBm TX output power across its supported Sub-GHz bands (779–787 MHz, 863–870 MHz, 902–928 MHz), as specified in Microchip's DS70005302A datasheet. This value is achieved using the integrated AT86RF212B transceiver's PA stage and is validated under 3.3 V supply conditions with appropriate matching network design.
Does the ATSAMR30E18A-MUT include an integrated 32.768 kHz crystal oscillator?
No, the ATSAMR30E18A-MUT does not integrate a 32.768 kHz crystal oscillator. Unlike the SAMR30G variant, it requires external 32.768 kHz crystal connections to PA00 (XIN32) and PA01 (XOUT32) to enable RTC calendar functionality and low-power sleep timing. This is confirmed in DS70005302A, Section 1 Configuration Summary.
How many general-purpose I/O pins does the ATSAMR30E18A-MUT provide?
The ATSAMR30E18A-MUT provides 16 programmable GPIO pins, as documented in Microchip's DS70005302A Table 1-1 (Configuration Summary) and validated in the pin multiplexing table (Section 6.1). These include PA00–PA19, PB02–PB03, PB22–PB23, PA22–PA25, PA27–PA28, PA30–PA31, and PB30–PB31 - totaling 16 user-accessible I/Os after accounting for dedicated RF, debug, and oscillator functions.
Which IEEE 802.15.4 modulation schemes are supported by the ATSAMR30E18A-MUT?
The ATSAMR30E18A-MUT supports BPSK (20 kb/s and 40 kb/s) compliant with IEEE 802.15.4-2003/2006/2011, and O-QPSK (100 kb/s and 250 kb/s) compliant with IEEE 802.15.4-2006/2011. It also supports O-QPSK at 200/400/500/1000 kb/s for proprietary high-data-rate modes, as detailed in DS70005302A Section 1.1 Features.
Is the ATSAMR30E18A-MUT pin-compatible with any other Microchip SAM R30 variants?
The ATSAMR30E18A-MUT is not pin-compatible with the 48-pin ATSAMR30G18A-MUT due to differing pin count, I/O mapping, and missing features (e.g., XOSC32K, full PTC). However, both share identical 256 KB Flash, 32 KB SRAM, and core RF architecture. Migration requires PCB redesign but preserves firmware compatibility at the HAL and driver level.
