ATSAMR21E17A-MUT is a Multi-Interface Transceiver module, that enables communication over multiple networks in the 2.4 GHz ISM Band. It comes with an integrated ARM Cortex-M0+ processor, with a low power 32-bit RISC core. Using an innovative transceiver architecture, ATSAMR21E17A-MUT is able to provide an optimized wireless performance, featuring sub-GHz radio frequencies, while keeping low power at the same time. Due to its low power consumption it is ideal for applications where energy efficiency is of paramount importance.
ATSAMR21E17A-MUT is a member of the R-series ICs, and has an array of advantages that make it perfect for RF communications. The main benefits of using the ATSAMR21E17A-MUT are the low power operation, supplemented by the wide range of interfaces that can be connected to the module, including UART, SPI, I2C, and USB. This makes it a powerful transceiver unit for numerous embedded applications, including medical devices, tracking and monitoring, home security systems, and more.
The working principle of ATSAMR21E17A-MUT centers around its industry-leading transceiver architecture. This architecture is based around the S-Band, which reduces the size of the signal while maintaining a robust link. By using of the S-Band, the transceiver is able to communicate over multiple networks using a single RF hopping frequency within the 2.4 GHz ISM Band, while still maintaining a secure link. The receiver is connected to both a low noise amplifier to detect incoming signals, and a demodulator to decode the signals, before passing them on to the host processor.
Due to its built-in processor, ATSAMR21E17A-MUT can also be used as an embedded processor by utilizing its pre-installed firmware. It can be programmed using a straightforward command set called “Program Memory Flexibility”. This allows for flexible configurations of memory organization and interrupts, providing greater control over how the module will function. It also provides a low power operation thanks to the fact that interrupt vectors are constantly updated, reducing power consumption when the device is idle.
ATSAMR21E17A-MUT is a powerful IC that combines sub-GHz RF communication and a low power ARM Cortex-M0+ processor with an intuitive interface set, making it an ideal choice for numerous applications. In addition, the device’s low power draw, coupled with the wide range of communications protocols that it supports, make it an exceptional RF transceiver IC in its class.
