MCHPATSAMR21G18A-MUT
Overview
The ATSAMR21G18A-MUT is a highly integrated System-on-Chip (SoC) that combines a low-power ARM Cortex-M0+ microcontroller with an IEEE 802.15.4 compliant 2.4GHz radio. It features 256kB of Flash and 32kB of SRAM, providing a compact solution for wireless mesh networking applications like Zigbee and Thread.
Why Choose This Part
This SoC simplifies RF design by integrating the transceiver and MCU into a single 48-pin VFQFN package, reducing PCB footprint. Its ARM Cortex-M0+ core supports 12 DMA channels and multiple SERCOM interfaces, allowing for efficient peripheral management without waking the CPU core.
Applications
