Product details
Overview
ATSAMR30M18AT-I/RM100 from Microchip is a fully certified, compact 802.15.4 Sub-GHz SiP module integrating an ARM Cortex-M0+ MCU (48 MHz), 256 KB Flash, 40 KB RAM, and an ultra-low-power transceiver for 780/868/915 MHz ISM bands. It delivers self-healing mesh networking via MiWi, 6LoWPAN, and Zigbee PHY, targeting battery-powered wireless sensors and home automation endpoints.
For engineers reviewing the ATSAMR30M18AT-I/RM100 datasheet, ATSAMR30M18AT-I/RM100 pinout, ATSAMR30M18AT-I/RM100 application, or ATSAMR30M18AT-I/RM100 equivalent, key selection criteria include regulatory-compliant RF front-end (FCC/ETSI), integrated AES-128 crypto engine, 16 GPIOs, USB 2.0 full-speed interface, and SERCOM-based serial peripheral flexibility.
Technical Context
The ATSAMR30M18AT-I/RM100 implements IEEE 802.15.4-2006 compliant PHY/MAC with automatic retransmission, 32-bit MAC symbol counter, and hardware-accelerated AES-128 encryption. Its transceiver supports O-QPSK modulation in 780/868/915 MHz bands with integrated harmonic filtering and FCC/ETSI certification.
It embeds a 48 MHz ARM Cortex-M0+ core with 256 KB on-chip Flash and 40 KB SRAM, plus a 12-bit 350 ksps ADC, I²C up to 3.4 MHz, and two configurable SERCOM units-enabling UART, SPI, or I²C peripherals without external components.
