Device Overview

Summary

The ATSAMR21G18-MR210UA is a 19 x 20mm wireless module with a solder mount footprint. It integrates an ATSAMR21G18 IC together with a serial flash and a crypto authentication device. The ATSAMR21G18-MR210UA is based on the ATSAMR21G18A, a IEEE 802.15.4 compliant single chip that combines an ARM® Cortex®-M0+ based 32-bit microcontroller and best-in-class 2.4GHz RF transceiver. It offers an excellent RF performance, with a link budget of 103dBm while consuming 50% less active current than existing offerings.
