Product Specification
Product Name: Zigbee Module
Model Name: DSM-020
1. Introduction
1.1 Purpose& Description
The DSM-020 is a low-power, embedded Zigbee module. The module consists of a EFR32MG13P732 highly integrated wireless RF processor chip and a small number of peripheral devices. It has a built-in 802.15.4 PHY/MAC Zigbee network protocol and a large number of library functions.
The DSM-020 embeds a low-power 32-bit ARM Cortex-M4 core, 512KByte Flash program memory, 64KB RAM data memory, and a wealth of peripheral resources. The DSM-020 is a FreeRTOS platform that gathers all Zigbee MAC and TCP/IP libraries into one place. It enables users to build on the product and develop embedded Zigbee products that suit their individual needs.
