eXtreme Low Power Solutions for Wearable Applications Overview Small Form Factor Extremely small, wearable devices are quickly becoming popular, either as stand-alone accessories or as companions for use with a smartphone. New wearable technology is being developed for many applications including medical diagnostics, fitness monitoring and personal entertainment. Every millimeter counts in wearable device design, forcing you to view the system from a different perspective than that of typical embedded applications. Our PIC MCU portfolio also takes a different approach, giving you the functional “building blocks” needed to architect your system with as few external components as possible. Developers of wearable devices face many unique design challenges. To be successful, a wearable application must have long battery life, be extremely space efficient and offer effortless connectivity to the Cloud—while at the same time protecting sensitive user data against intrusions of privacy. Microchip’s long-standing focus on enabling our customers to develop highly-integrated, cost-effective embedded systems has given rise to an MCU portfolio that meshes perfectly with the needs of wearable designs. Ultra-Tight Power Budgets Wearable devices run on batteries that are expected to last for weeks or months. To extend the battery life in these power-sensitive applications, PIC® microcontrollers with eXtreme Low Power (XLP) technology offer the industry’s lowest currents for Run and Sleep modes. When sensing data and executing code, wearable devices need to process and transmit information as fast and efficiently as possible, and then go back to sleep in order to optimize battery life. PIC MCUs with XLP technology operate as low as 30 μA/MHz and with speeds up to 16 MIPS, enabling power-efficient applications. Typically, wearable devices spend most of their time in sleep mode until they are needed to measure biometric data. PIC MCUs with XLP technology consume sleep currents as low as 9 nA with flexible wake-up sources and a variety of low-power modes, retaining state, RAM and time. Also, PIC MCUs offer supervisory circuits to protect stored data and to ensure safe operation when batteries are depleted or changed. Flexible, integrated Core Independent Peripherals are designed to take the load off the CPU and reduce the amount of code needed. PIC MCUs enable you to combine several functional tasks onto a smaller, more cost-effective MCU than previously possible. In addition, on-chip Intelligent Analog peripherals (including ADCs, op amps, Slope Compensation, and Zero Cross Detect) on PIC MCUs can be configured to autonomously provide data to the digital peripherals from sensors, touch buttons and feedback circuits for low latency and quick system response. These technologies combine to create a higher-performance system, without higher MCU clock speed and power consumption. Lower power consumed equals a smaller battery. More space savings can be achieved by taking advantage of our wide array of lowprofile and small-footprint QFN packaging. PIC MCUs are always the right choice for optimizing wearable applications for size and BOM cost. Effortless Connectivity Wireless communication is the preferred method of moving data between a wearable device and a smartphone for display, control or cloud computing. Bluetooth® and Wi-Fi® are emerging as the standard communication channels for wearable devices. For the ultimate in flexibility and ease of design, our wireless modules offer drop-in functionality. Modules are available for Wi-Fi, Bluetooth 2.1 and Bluetooth 4.2 (Bluetooth Low Energy.) A space-saving module with integrated antenna and on-board software stack enables you to add wireless connectivity to any design with a minimum of effort. To save even more time and money, these modules have already been certified by the FCC and international agencies. Securing Personal Data A growing number of wearable applications include some personal data and offer a cloud-based connection to access that data from a remote location. Encrypting personal data on the device adds another level of privacy when using Internet-based storage. PIC MCUs with an integrated hardware crypto engine offer data encryption without sacrificing power consumption and battery life for wearable applications. These devices feature industry-standard support, up to 256-bit AES and Triple DES. The hardware crypto engine saves power, performing encryption 10× faster than software algorithms, with a quick return to low-power sleep modes. Also, these MCUs include a random number generator for creating a secure encryption key and dedicated, secure RAM, secure OTP-based key management with self destruct on tamper detect through pin. We also provide extensive security software libraries for devices that do not feature an integrated hardware crypto engine.
