MXR-EM20
Zigbee Transceiver Module

Description

The MXR-EM20 is a 2.4 GHz RF transceiver designed for low-power and low-voltage wireless applications. The MXR-EM20 includes a digital direct sequence spread spectrum baseband modem and an effective datarate of 250 kbps. The MXR-EM20 is compatible with a licensed Ember networking stack. The MXR-EM20 is a low-cost, highly integrated solution for robust wireless communication in the 2.4 GHz unlicensed ISM band. It is designed to comply with world-wide regulations covered by EN 300 440 (Europe), CFR47 Part 15 (US) and ARIB STD-T-66 (Japan). The MXR-EM20 provides extensive hardware support for packet handling, data buffering, burst transmissions, data encryption, data authentication, clear channel assessment, link quality indication and packet timing information.

The configuration interface and transmit / receive FIFOs of the MXR-EM20 are accessed via a SPI interface.
