The ETRX3587 is a so-called RF Transceiver Module for short-range wireless communication. It is designed according to low-power, wide-area networking requirements and supports Zigbee, IEEE 802.15.4, 6lowpan, Point-to-Point protocol and mesh networks. It features integrated radio transceiver, ARM Cortex-M3 based microcontroller and user-programmable MCU memory.

Applications of ETRX3587 include smart home automation, industrial automation, personal medical care, home security, agricultural monitoring, and energy management. The module also provides embedded system developers a development basis for low power, low cost, short-distance wireless communication projects.

The working principle of ETRX3587 is closely related to the integrated system design. Firstly, its low-frequency operating clock is powered by an on-chip circuitry consisting of low-noise oscillator, voltage regulation, a programmable digital clock generator and a noise-shaping circuit. Secondly, the RF transceiver module utilizes a high frequency operating clock supplied by an external crystal to run the main processor and two baseband digital signal processors (DSPs).

The RF transceiver module works by initializing and power-cycling the system. Once power is applied, the module will search for an available RF network, determine its channel and synchronize with it. If there is none, it will establish its own network. Once these steps are completed, it can transmit and receive data and commands between nodes in the network.

The ETRX3587 also provides an on-chip antennae diversity switch to ensure constant fast and reliable signal connections suitable for data communication. This is accomplished by setting the RSSI to best level before receiving data. Simultaneously, it also provides quad-band operation, infrared signal transmission, customized RF output power and data rate, connectionless networking and configurable 802.15.4 MAC layer.

In conclusion, the ETRX3587 RF Transceiver Module is a comprehensive integrated system that meets the requirements for low-power, low-cost wireless communication of short-range networking. This module offers various built-in security features with automatic RF channel detection, RF calibration, error detection and CRC verification features. Such features make this module an ideal choice for many wireless network and embedded system applications.
