The EM357-ZRT is a RF transceiver IC designed for ultra-low-power short range wireless networks in applications where size, power consumption, and reliability are key. This IC uses a highly integrated architecture to combine both the radio and the microcontroller functions into one single chip, delivering the ultimate combination of radio performance, low-power consumption, and adaptability, while maintaining a small footprint.

The application fields of EM357-ZRT are wide, ranging from medical monitoring, home/building automation, smart metering, security, and agricultural monitoring/control, to a host of other uses. It is also an ideal solution for applications that require high data rate communications but have limited or no access to power outlets.

The EM357-ZRT is designed with a highly integrated architecture, combining both the radio and the microcontroller functions into one single chip. The chip is equipped with a radio chip that features radio transceiver, amplifier, modulator, and demodulator, and two low power 32-bit microprocessors. The radio chip operates on the SIGFOX protocol in the 868MHz frequency band with 433baud data rate. The integrated antennas allow for a truly low-profile and sleek design.

In terms of its working principle, when the EM357-ZRT receives a signal, the radio chip modulates the signal, amplifies it, and then demodulates it for further processing. This demodulated signal is then passed to the two low power 32-bit microprocessors, which carry out the necessary tasks like decoding the signal and making decisions based on the received information. Once the decision is made, the radio chip modulates the signal and sends it back out.

The EM357-ZRT is an incredibly powerful and efficient device that enables reliable wireless communications with ultra-low power consumption and the utmost in reliability. Its wide range of applications and sleek design make it an ideal solution for a variety of applications in both industrial and consumer use.
