In today's smart device market, wearable devices account for more and more, and the market potential is huge. According to the latest report released by international data company IDC on June 28 this year, in the first quarter of 2017, the global total shipment of wearable devices reached 24.7 million, an increase of 17.9%; driven by smart watches and smart apparel, The global wearable market will double in size in 2021.
At the same time of rapid development, the competition in the wearable market is becoming more and more fierce. Wearable device manufacturers must design differentiated wearable products in the short term, but there are no mature development solutions on the market to meet their needs. In response to this challenge, ON Semiconductor, which promotes energy-efficient innovation, has introduced the industry's first truly scalable wearable technology design platform to help more manufacturers accelerate the design and development of feature-rich designs that are highly resounding for consumers. Solved the problems faced by current wearable device companies.
ON Semiconductor leads the market with broad capabilitiesThrough long-term investment in innovative technologies and strategic acquisitions, ON Semiconductor has grown into a trial company with annual sales of approximately $5 billion, with comprehensive mobile device power and data management solutions. ON Semiconductor's line of energy-efficient power management, analog, sensor, logic, timing, interworking, discrete, system-on-a-chip (SoC) and custom devices in automotive electronics, communications, industrial, military and aerospace, and consumer And target markets such as computers have a wide range of applications and outstanding performance.
In the wireless and wearable segments, ON Semiconductor continues to focus on the three areas of smartphones/tablets, consumer wearables (non-medical), and smart charging and interoperability, with a broad product lineup and capabilities. In the wearable arena, ON Semiconductor is leading the way in many areas, including power management, battery FETs, wireless and wired charging solutions, fuel gauge solutions, AC-DC adapters, EEPROMs, image sensors and more. Package advantages (Figure 2), these advantages can help create scalable, high-performance, long-life, small form factor, low-power wearable devices.

Industry's first wearable development kit for one-stop solution development needsBased on the needs of the wearable market, ON Semiconductor has introduced the industry's first truly scalable wearable reference design platform, the WDK1.0. The flexible development kit includes hardware, firmware, integrated development environment (IDE) and downloadable SmartApp. Create everything from simple fitness trackers to sophisticated smart watches.
Wearable device manufacturers have different standards for product design, but have consistently high requirements for low power consumption, charging methods, processor performance, size, wireless connectivity, human-machine interface, and sensing capabilities. ON Semiconductor The WDK 1.0 fully satisfies these needs. In order to develop different products, customers only need to replace the processor, MCU, and different screens (or products without screen), and write code, compile, debug, etc. based on the software reference design, so as to accelerate the completion. Wear technical projects to shorten time-to-market and reduce related engineering investments.
The NCP6915 power management IC in the WDK1.0 kit comes with a programmable DCDC and 5 LDOs to accommodate a variety of output voltages while achieving power savings and energy savings. The design engineering team can also make more extensions through the GPIO interface to meet the needs of different products. The kit is also equipped with the NCP1855 battery charger IC, LC709203F fuel gauge IC and a 10W (W) rated SCY1751 wireless charging front controller that supports AirFuel compatible magnetic resonance wireless charging. According to the specific settings, the battery life can reach 24 to 36 hours, and the wired charging is completed within 1 hour, and the wireless charging is completed within 2 hours. As the industry's first wearable solution to support AirFuel's magnetic resonance wireless charging, WDK 1.0 will provide reference and guidance for the future design of wearable devices. In addition, it has a MEMS-based FIS1100 inertial measurement unit that includes a 3-axis gyroscope for multi-dimensional motion tracking and a 3-axis accelerometer. It also comes with an embedded temperature sensor and an LC898301 driver IC for haptic feedback.

The key to WDK 1.0 is its wireless connectivity, given that Bluetooth Low Energy (BLE) is a major connectivity protocol for the wearable market.
ON Semiconductor has partnered with Nordic Semiconductor, a leader in Bluetooth low-power technology, to provide ultra-low-power nRF52832 multi-protocol system-on-chip (SoC) from Nordic Semiconductor. The chip features a 32-bit ARM® CortexTM processor core and a 2.4GHz transceiver supporting Bluetooth Low Energy (BLE) and other related wireless technologies.
The kit is also complemented by a SmartApp that can be downloaded directly from the Android PlayStore and Apple AppStore to view basic motion data such as steps, calories burned, distance traveled, and activity time, as well as screen brightness adjustment, clock Surface control, alarm settings, and human-machine interfaces such as fitness goals. The kit comes with an Eclipse-based integrated development environment (IDE) that gives the engineering team all the resources they need to quickly create a design and then debug the code. In addition, the very intuitive Project Wizard provides engineers with many useful examples of wearable related projects, further accelerating the development process.
