我对Nordic蓝牙芯片的印象 精

今天看了一下Nordic蓝牙芯片的技术和产品介绍，很受触动，有几个方面印象特别深刻：
1.一系列的协议栈（Nordic 称为：SoftDevices）：S112,S113,S122,S132,S140,S212,S312,S332,S340;
2.PPI事件系统：programmable peripheral interconnect (PPI) ；
3.柔性正交电源管理系统（flexible orthogonal power management system）；
4.EasyDMA;
5.内存缓存技术Memory Cache；
6.硬件保护；
7.丰富的接口；
8.参数归类比较，一目了然。
从中可感受到Nordic对于其产品和技术的用心和专心。
