随着恩智浦收购飞思卡尔，他们采购了包括Kinetis系列微控制器产品在内的整个产品组合。
Kinetis K8x MCU的一个特殊系列在其目标应用之一上非常有趣：智能可穿戴设备。
这是当今技术领域最热门的应用之一，而Kinetis K8x MCU是融入该领域设计的理想选择。
与Kinetis系列中的其他MCU相比，Kinetis K8x系列产品的主要区别在于其高级安全性。
在当今的物联网（IoT）环境中，安全性变得越来越受到关注，因为我们互联世界中的所有东西都可以通过网络访问。
没有人希望窥探他们的私人信息或黑客为了邪恶的目的而接管他们的设备。
因此，Kinetis K8x系列提供的高级安全性将是可穿戴设备和其他便携式设备设计的理想选择。
这些高级安全功能包括支持加密固件更新的引导ROM，支持公钥加密，带边带攻击保护的硬件AES加速，以及从外部NOR闪存自动解密和执行。
添加了所有这些安全性改进，同时保持与先前版本的Kinetis设备的高度向后兼容性。
K8x系列的低功耗也是当今可穿戴/便携式设备的必备功能。
这些器件在低功耗运行时仅需要210μA/ MHz的动态电流，并且在状态保持模式下仅需要低至5μA的电流。
此外，智能片上集成可节省大量BOM。
最重要的是，Kinetis K系列支持一整套开发工具，软件和支持，包括Freedom K82开发平台（如下所示）。
恩智浦Freedom K82开发平台
这是一款低成本电路板，可用作Kinetis K82，K81和K80器件的开发平台。
它与Arduino™R3引脚布局兼容，可以使用各种扩展板。
此外，通过外围设备实现快速原型设计，例如六轴数字加速度计和磁力计（用于完整的eCompass功能），三色LED和两个用于直接交互的用户按钮，2x32Mb QuadSPI外置闪存，FlexIO摄像头，
以及用于Bluetooth®和2.4 GHz无线电附加模块的触摸板和接头。
使用该板快速开发和原型化您的应用程序可以显着缩短项目上市时间。
除智能可穿戴设备外，Kinetis K8x系列MCU在其他应用中具有广阔的前景，如便携式健康和健身设备，游戏控制器，智能家居自动化和安全，楼宇控制，销售点设备和活动等。
健康监测器。
如果您正在寻找能够提供低功耗，易于使用的开发工具的MCU，并且不受窥探，那么Kinetis K8x系列非常值得您考虑。

With NXP’s acquisition of Freescale they procured their entire product portfolio including the Kinetis line of microcontroller products. One particular family, the Kinetis K8x MCUs, is particularly interesting regarding one of its target applications: smart wearable devices. This is one of the hottest applications in the technology world today and the Kinetis K8x MCUs are ideal candidates for being incorporated into designs in this field.
The main difference the Kinetis K8x family offers over other MCUs in the Kinetis line is its advanced security. In the today’s Internet of Things (IoT) climate, security is becoming more of a concern since everything in our connected world is potentially accessible through the web. No one wants prying eyes on their private information or hackers taking over their devices for nefarious purposes. Therefore, the advanced security that the Kinetis K8x family offers would be ideal for wearable and other portable device designs.
These advanced security capabilities include boot ROM to support encrypted firmware updates, support for public key cryptography, hardware AES acceleration with side band attack protection, and automatic decrypt and execute from external NOR Flash memory. All of these security improvements were added while keeping a high level of backward compatibility to prior versions of Kinetis devices.
The low power consumption of the K8x family is also a must for today’s wearable/portable devices. These devices require only 210 µA/MHz in low-power operation with dynamic currents and only require a miserly 5 µA in state retention mode. Additionally, smart on-chip integration provides substantial BOM savings.
To top it all off, the Kinetis K series is supported by a comprehensive set of development tools, software, and enablement including the Freedom K82 development platform (shown below).
![]() NXP's Freedom K82 Development Platform
This is a low-cost board that can be used as a development platform for the Kinetis K82, K81, and K80 devices. It is form-factor compatible with the Arduino™ R3 pin layout which enables the use of a wide range of expansion boards. Furthermore, rapid prototyping is enabled by peripherals such as a six-axis digital accelerometer and magnetometer (for full eCompass capabilities), a tri-colored LED and two user push-buttons for direct interaction, 2x32Mb QuadSPI external flash, a FlexIO camera header, and touch pads and headers for use with Bluetooth® and 2.4 GHz radio add-on modules. Using this board to develop and prototype your application quickly can significantly reduce project time to market.
In addition to smart wearable devices, the Kinetis K8x family of MCUs has a promising future in other applications such as portable health and fitness devices, gaming controllers, smart home automation and security, building control, point-of-sale devices, and activity and wellness monitors.
If you’re looking for an MCU that offers low-power consumption, easily available development tools, and that is secure from prying eyes, the Kinetis K8x family is highly worth your consideration.
