href="http://cp.ck365.cn/zhinengdianwang/" target="_blank"><strong class="keylink">智能电网</strong></a>标准的单片无线微<a href="http://cp.ck365.cn/kebianchengkongzhiqi/" target="_blank"><strong class="keylink">控制器</strong></a>的样片。新款微控制器的设计目的是减少停电次数和二氧化碳排放量，同时还可支持未来的生活方式，包括插电式电动车充电。</p> <p style="text-align: center"><img alt="QQ截图20120510094215.jpg" width="419" height="267" src="http://www.ck365.cn/file/upload/201301/19/17/3ifyr4f3uu0.jpg" /></p> <p>STM32W微控制器是首批取得IEEE802.15.4认证的平台，可支持新的ZigBee®SmartEnergyProfile2.0(SEP2.0)协议，该标准定义了智能电网环境，以实现一个更节能的世界。使用基于最新的互联网协议(IPv6)的无线通信协议栈(ZigBeeIP)，扩大了不同厂商之间以及他们的物理层芯片之间的互操作性。在其它的SEP2.0先进功能方面，STM32W还可支持电费预付服务、负载响应和电力需求管理；微控制器及其功能可实现节能家庭和建筑。</p> <p>智能电网产品，包括联网设备，例如内置STM32W微控制器的电器、电表和基础设施监视设备，被认为能够降低用电高峰时的负荷，提高电网运行的稳定性，有助于降低耗电量，提高各种再生能源的管理效率，例如风力发电和太阳能发电。据美国能源局报告显示，智能电网应用有助于美国电力工业把二氧化碳排放降低12个百分点，这相当于关闭66家普通火力发电站。</p> <p>意法半导体的STM32W基于ARM®Cortex™-M3处理器内核，芯片存储器容量达到256KB，并提高了代码密度，让开发人员能够开发符合SEP2.0标准的智能电网应用。除了在芯片上实现的IEEE802.15.4标准射频接口外，还拥有16位定时器、1个加密加速器和12位模数<a href="http://cp.ck365.cn/zhq/" target="_blank"><strong class="keylink">转换器</strong></a>等功能，对于设计人员开发经济型独立无线传感器和控制解决方案也非常重要。</p> <p>选用STM32W开发新一代无线产品的开发人员还受益于这款产品与STM32微控制器的密切关系。沿袭STM32产品家族的优良基因，STM32W基于相同的ARMCortex-M3处理器内核，可与庞大的STM32产品家族相兼容。而另一个优势是STM32W也采用开发人员熟悉的STM32开发工具。此外，庞大而活跃的STM32在线开发者社区提供技术支持、开发知识和第三方开发工具。</p> <p>STM32W的主要特性:优异的IEEE802.15.4射频性能ARMCortex-M3的先进<a href="http://cp.ck365.cn/dianyuanceshi/" target="_blank"><strong class="keylink">电源</strong></a>管理功能STM32W全系产品都具有很强的价格竞争力宽广的存储容量选择范围，满足各种应用要求强大的支持工具:免版税的IEEE802.15.4协议栈和软件库三个互补的开发工具真正的单片解决方案意法半导体已开始向主要客户提供STM32W样片。所有产品都采用48引脚QFN48封装，低容量版还可以选择40引脚QFN40封装。</p></div>
