The IoT embraces many products, technologies and applications. However, in terms of numbers of units, the largest segments of the IoT market will comprise small portable or wearable electronic devices that derive power from tiny batteries, or perhaps from energy harvesting. Many of these devices will gather sensor data which is processed then sent to the Internet via an access node or gateway, using one or more wireless protocols as the first part of the link.

There is much debate around which wireless protocols are likely to dominate in the IoT world. However, most industry observers expect Bluetooth® Smart to be the protocol of choice in many instances, not least for consumer products where many Internet connections will be made via a smartphone gateway. Smartphones, set-top boxes, televisions and a host of other consumer electronic products already incorporate Bluetooth radios, and Bluetooth Smart is both lower power and more secure than Wi-Fi. Analyst IHS predicts that by the end of 2015 every mobile platform will ship with Bluetooth Smart Ready functionality.

Functional integration is a key strategy for minimizing power consumption. If the baseband processor in a Bluetooth radio has sufficient resources to run the application too, this not only minimizes the size of the solution but also its cost and energy consumption. Of course, integration must go hand-in-hand with effective power management. The on-chip resources needed for each specific task must only be fully powered when they’re needed. It’s even possible to ‘tune’ a processor so that its clock speed, and hence performance, is controlled dynamically in line with the performance needed at the time.

Example applications

雷竞技电竞平台对话框半导体designs and manufacturesSmartBond™ Systems-on-Chip(soc)。这些微小的、超低功耗蓝牙Smart components integrate a Bluetooth low energy radio with an ARM® Cortex®-M0 application processor and intelligent power management. Measuring just 2.5 mm x 2.5 mm in a WLCSP they need just five external components for a complete hosted Bluetooth Smart solution. Access to the ARM® processor is available via 32 GPIOs. Energy requirements are so modest that one company developed a smart insulin injection pen for diabetics where removal and replacement of the pen’s cap produces sufficient energy for the SmartBond SoC to capture the exact dose of insulin delivered and send that information to a smartphone app.

最近，SmartBond产品系列已被扩展为包括带片上闪光灯的版本DA14583，可在空中升级（Suota）中使用软件升级在现场升级的最终产品。雷电竞官网登录还有两种新的应用优化变体：DA14581，用于基于A4WP标准的松散耦合，高谐振电感充电，以及蓝牙智能遥控单元（RCU）的DA14582。DA1582集成了模拟音频编解码器，并针对使用语音识别，运动控制或手势识别的远程控制单元进行了优化。

SmartBond系列中的最新设备，DA14680，甚至采用功能集成，也进一步实现了可调处理电源，用于传感器控制的专用电路，以及针对可穿戴物优化的模拟和数码外围设备。它有效地是一个“可穿上芯片”，看看它如何释放消费产品设计师的创造力，易于实施，微小的尺寸和最小的电源要求，这将是令人着迷的。
