<div>
<p >1、开头我们先聊聊，关于南京中科微2.4GHz无线MCU芯片（Ci2451、Ci2454、CSM2433)是建立在现有的2.4GHz射频芯片基础上面，它的内部是集成了8位RISC内核，且集成丰富的MCU资源、更小的尺寸可以来满足设计中的各种内存、功率、尺寸要求，充分缩短了市面上2.4GHz无线产品设计周期并在产品成本上有所优化。</p>
<div style="text-align: center;"></div>
<p >2、而今天我们来聊聊相似的两颗2.4GHz无线MCU芯片：Ci2451和Ci2454，看看它们的共同特性以及区别之处都分别有哪些呢？</p>
<p >①首先从无线收发器的特性来看，Ci2451与Ci2454它们是没有区别的。</p>
<div style="text-align: center;"></div>
<p >②再看2.4GHz无线MCU芯片特性对比表↓</p>
<div style="text-align: center;"></div>
<p >③由此我们可以看出，在MCU的特性上，Ci2454会比Ci2451的性能更加多一点，在产品升级上可以为更多功能提供可开发的可能空间，而Ci2451会更有性价比，适合低成本要求生产的产品。</p>
<div style="text-align: center;"></div>
<p >④而在其他特性上，Ci2454与Ci2451不仅宽电源电压范围相同，都只需很少的外围器件，且系统应用成本低，简化了系统设计。这无疑大大地帮助用户在实现产品开发的过程中，可以有效减少了PCB板的占用面积和整体产品尺寸，降低BOM成本，可以缩短整个研发周期，对于低成本的应用可以做到更好的产业迭代和产品升级，且方便更快地将产品投入市场。</p>
