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.

5. Production Guide
The storage conditions for the module after it has been shipped are as follows:
1. The moisture resistant bag must be stored at a temperature below 30℃, and under a relative
humidity below 85%.
2. The shelf life of dry packed products is 6 months following the packaged date important
information.
3. All line workers must wear anti-static wrist straps and anti-static clothing throughout the entire
production process.
4. It is strictly prohibited to allow a module to come into contact with water or other contaminants
during operations.
