原创 CC2540 头文件下载

在2010年底TI推出了完整形蓝牙低功耗单模式芯片CC2540,　主要面向手机附件、消费电子、计算机接口设备、健康、医疗、个人运动设备，可以使用钮扣电池作为电源。

 和CC2530一样，它还是8051的内核，甚至CC2530RF之外的程序可以直接在CC2540上运行。采用QFN40　6mm*6mm的封装，内部FLASH有128KB,256KB两种规格，而RAM统一为8K.

 IAR for 8051 7.51A以上版本支持cc2540的开发。TI原装开发工具，售价$99。目前还没有国产的开发工具，不过相信到2011年夏秋就会有了。目前已经有人开始玩CC2540，但是发现直接安装的IAR for 8051 7.51A并没有cc2540的头文件iocc2540.h和仿真用的cc2540.ddf文件。我把它挂在这里，用到这个补丁的就自己下。
