E18系列模块采用美国德州仪器公司原装进口CC2530射频芯片，芯片内部集成了8051单片机及无线收发器，部分模块型号内置PA功率放大器增加通信距离。

出厂自带固件基于ZigBee3.0协议实现的串口数据透传，支持ZigBee3.0协议下各种指令命令。

经实测，对市面上大多数ZigBee3.0产品有着非常良好的兼容性。

1.2ZigBee 3.0优势E18系列模块固件基于Z-Stack3.0.2协议栈（ZigBee 3.0），该版本为CC2530/CC2538系列芯片最优协议栈，因此我司也此基础上做了许多优化，确保系统长期稳定运行。

ZigBee3.0与早前版本的应用方式区别：1.组网方式发生变化：ZigBee 3.0取缔了一上电就组网的方式，而是根据实际需要进行组网。

任何设备在出厂状态下是无网络状态，协调器需要运行“formation”（调用bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_FORMATION)）来新建网络，然后再运行"Steering"(调用bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_STEERING))打开网络，打开网络默认时间180秒，可通过广播"ZDP_MgmtPermitJoinReq"的方式将打开网络提前关闭。

If the usage and operation conditions specified in the datasheet are not met, the wire insulation may be damaged or dissolved.•Do not drop or impact the components, the component may be damaged.•Würth Elektronik products are qualified according to international standards, which are listed in each product reliability report. Würth Elektronik does not warrant any customer qualified product characteristics beyond Würth Elektroniks’ specifications, for its validity and sustainability over time.•The responsibility for the applicability of the customer specific products and use in a particular customer design is always within the authority of the customer. All technical specifications for standard products also apply to customer specific products.Product specific:Soldering:•The solder profile must comply with the technical product specifications. All other profiles will void the warranty.•All other soldering methods are at the customers’ own risk.Cleaning and Washing:•Washing agents used during the production to clean the customer application might damage or change the characteristics of the wire insulation, marking or plating. Washing agents may have a negative effect on the long-term functionality of the product. Potting:•If the product is potted in the customer application, the potting material might shrink or expand during and after hardening. Shrinking could lead to an incomplete seal, allowing contaminants into the core. Expansion could damage the component. We recommend a manual inspection after potting to avoid these effects.Storage Conditions:• A storage of Würth Elektronik products for longer than 12 months is not recommended. Within other effects, the terminals may suffer degradation, resulting in bad solderability. Therefore, all products shall be used within the period of 12 months based on the day of shipment.•Do not expose the components to direct sunlight.•The storage conditions in the original packaging are defined according to DIN EN 61760-2.•The storage conditions stated in the original packaging apply to the storage time and not to the transportation time of the components. Packaging:•The packaging specifications apply only to purchase orders comprising whole packaging units. If the ordered quantity exceeds or is lower than the specified packaging unit, packaging in accordance with the packaging specifications cannot be ensured. Handling:•Violation of the technical product specifications such as exceeding the nominal rated current will void the warranty.•Applying currents with audio-frequency signals may result in audible noise due to the magnetostrictive material properties.•Due to heavy weight of the components, strong forces and high accelerations may have the effect to damage the electrical connection or to harm the circuit board and will void the warranty.•Please be aware that products provided in bulk packaging may get bent and might lead to derivations from the mechanical manufacturing tolerances mentioned in our datasheet, which is not considered to be a material defect.•The temperature rise of the component must be taken into consideration. The operating temperature is comprised of ambient temperature and temperature rise of the component.The operating temperature of the component shall not exceed the maximum temperature specified.These cautions and warnings comply with the state of the scientific and technical knowledge and are believed to be accurate and reliable.However, no responsibility is assumed for inaccuracies or incompleteness.Würth Elektronik eiSos GmbH & Co.

The responsibility for the applicability and use in a particular customer design is always solely within the authority of the customer. Due to this fact it is up to the customer to evaluate, where appropriate to investigate and decide whether the device with the specific product characteristics described in the product specification is valid and suitable for the respective customer application or not.2. Customer Responsibility related to Specific, in particular Safety-Relevant ApplicationsIt has to be clearly pointed out that the possibility of a malfunction of electronic components or failure before the end of the usual lifetime cannot be completely eliminated in the current state of the art, even if the products are operated within the range of the specifications.In certain customer applications requiring a very high level of safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health it must be ensured by most advanced technological aid of suitable design of the customer application that no injury or damage is caused to third parties in the event of malfunction or failure of an electronic component. Therefore, customer is cautioned to verify that data sheets are current before placing orders. The current data sheets can be downloaded at .3. Best Care and AttentionAny product-specific notes, cautions and warnings must be strictly observed. Any disregard will result in the loss of warranty.4. Customer Support for Product SpecificationsSome products within the product range may contain substances which are subject to restrictions in certain jurisdictions in order to serve specific technical requirements. Necessary information is available on request. In this case the field sales engineer or the internal sales person in charge should be contacted who will be happy to support in this matter.5. Product R&DDue to constant product improvement product specifications may change from time to time. As a standard reporting procedure of the Product Change Notification (PCN) according to the JEDEC-Standard inform about minor and major changes. In case of further queries regarding the PCN, the field sales engineer or the internal sales person in charge should be contacted. The basic responsibility of the customer as per Section 1 and 2 remains unaffected.6. Product Life CycleDue to technical progress and economical evaluation we also reserve the right to discontinue production and delivery of products. As a standard reporting procedure of the Product Termination Notification (PTN) according to the JEDEC-Standard we will inform at an early stage about inevitable product discontinuance. According to this we cannot guarantee that all products within our product range will always be available. Therefore it needs to be verified with the field sales engineer or the internal sales person in charge about the current product availability expectancy before or when the product for application design-in disposal is considered.
