ON Semiconductor unveils SiP solution for precision-sensing in portable medical devices
ON Semiconductor has introduced the Struix, a semi-customisable System-in- Package (SiP) solution, for precision sensing and monitoring in a variety of mobile medical electronics including glucose monitors, heart rate monitors and electrocardiogram analysers. The product is a response to the rapidly- evolving product development demands from within the portable medical market.
Struix, which means "stacked" in Latin, uses advanced die stacking technology to integrate a custom- designed analogue front-end (AFE) on top of an industry-leading 32-bit Application Specific Standard Product (ASSP) microcontroller (ULPMC10), to form a complete miniature system. By using standard and customisable components, Struix offers medical device manufacturers greater design flexibility.
"Advanced stacking technology enables Struix to achieve greater system integration and occupy less board space in medical devices than standalone solutions," explained Michel De Mey, senior director of consumer health solutions at ON Semiconductor. "Our SiP approach reduces design time, development risks and the costs associated with fully customised solutions. Design flexibility is further enhanced because the solution's ULPMC10 microcontroller can be easily updated with future microcontrollers from ON Semiconductor, without replacing the AFE, which is subject to FDA re-certification." The ULPMC10 microcontroller element of
Samsung mass producing industry's first, 20nm 6Gb LPDDR3 mobile DRAM
Samsung Electronics has begun mass producing its six gigabit (Gb) low-power double data rate 3 (LPDDR3) mobile DRAM, based on advanced 20 nanometer (nm) process technology. The company said that the highly-efficient new mobile memory chip will enable longer battery run-time and faster application loading on large screen mobile devices with higher resolution. "Our new 20nm 6Gb LPDDR3 DRAM
Struix processes signals using a 32-bit ARM Cortex-M3 core capable of running up to frequencies of 30 megahertz (MHz). The microcontroller incorporates 512 kilobytes (kB) on-chip Flash memory and 24 kB SRAM memory to store critical program and user data.
Designed to improve battery life in portable devices, ULPMC10 also offers enhanced performance with minimal dynamic and static power demands. Through on-chip charge pump-based power conversion and regulation, the microcontroller can operate at a current consumption of less than 200 µA/MHz. While in standby mode, current consumption remains below 500 nanoamperes (nA), a critical parameter for low-duty cycle medical devices.

provides the most advanced mobile memory solution for the rapidly expanding high- performance mobile DRAM market," explained Jeeho Baek, vice president, memory marketing, Samsung Electronics. "We are working closely with our global customers to offer next- generation mobile memory solutions that can be applied to a more extensive range of markets ranging from the premium to standard segments."
Samsung's new 6Gb LPDDR3 has a per-pin data transfer rate of up to 2,133 megabits per
second (Mbps). A 3GB (gigabyte) LPDDR3 package, which consists of four 6Gb LPDDR3 chips, can be easily created for use in a wide range of mobile devices. The new 3GB package is more than 20
percent smaller and consumes about 10 percent less energy than the currently available 3GB package with 6Gb LPDDR3 chips fabricated using Samsung's previously lowest process technology. This results in a mobile memory that is ultra-small, incredibly thin, lightning fast and significantly more power-efficient. Using Samsung's new 20 nanometer process also brings more than a 30 percent productivity gain, compared to the previous process. Samsung first applied 20 nanometer technology on 4Gb DDR3 for PCs in March, for the first time in the industry, and has now expanded its use to include the company's mobile DRAM.

Develop designs faster with the Pmod Adapter for Arduino Platforms
Maxim Integrated has launched a wide range of production-quality sensors using the Pmod-to- Arduino adapter. The MAXREFDES72# allows any board with Pmod connections to plug easily into Arduino-compatible microcontroller platforms and will enable design engineers to quickly create Internet of Things designs, and will give them access to a broader range of digital processors and applications.
Dialog Semiconductor's latest DSP audio codecs optimised to improve voice and audio experience
Dialog Semiconductor has announced the availability of two new audio DSP CODECs – the DA7322 and DA7323 – targeting applications with up to four analogue or digital microphones respectively. Featuring high levels of audio digital signal processor (DSP) functionality with a minimum power consumption requirement, these products are specifically developed for voice-centric applications found in the latest generation of tablets, wearables, webcam accessories and in-vehicle entertainment.
The new audio CODECs incorporate an integrated 24-bit DSP with an advanced voice engine package that provides an improvement of over 35dB signal-to-noise ratio (SNR) through the use of multi-channel beamforming, noise suppression and acoustic echo cancellation features. The result is a significant enhancement in speech performance with greatly improved sound quality for VoIP and voice recognition applications, which is particularly important for end users in a noisy environment. "There is an increasing need to improve the audio quality of voice calls," said Udo Kratz, Senior Vice President and General Manager, Business Group Mobile Systems at Dialog. "Independent of the ambient noise conditions the consumer is experiencing, both audio CODECs deliver a superior audio experience by significantly reducing unwanted noise while maintaining voice quality during VOIP calls on applications such as SkypeTM or LyncTM." Targeting wearables, a low power voice trigger is available on the DA7322 and DA7323 where over a dozen keywords can be

supported with over 95% accuracy without false triggering. This capability is demonstrated by the TrulyHandsfree always-on voice activation and recognition software provided by Sensory, which includes trigger to search, user-defined triggers, speaker verification and identification and multiple language support. Beamforming technology built into the DA7322 and DA7323 voice engine package has been designed to offer maximum flexibility in terms of microphone placements in order to support both endfire and multi-MIC configurations. The beamforming algorithm also has the ability to suppress a variety of stationary and non-stationary noise sources. The embedded DSP engine includes a suite of audio enhancement SmartEffects ranging from multi-band equalization to stereo widening. It also contains a psychoacoustic bass boost that can be enabled to improve perceived low frequency response for playback on low cost speakers, while dynamic range control and volume levelling offers more perceived loudness and consistent audio levels. The advanced accessory detection integrated on the CODECs supports 3- or 4- pole jack detection. The device can, therefore, automatically detect the type of headset being used, without the need for any external adapters. The DA7322 can support four analogue microphones. The DA7323, by contrast, offers support for three analogue or two pairs of stereo digital microphones.

Components in Electronics
The Pmod form factor has long allowed integration of professional-grade peripherals into engineering prototypes, especially on FPGA- based platforms. The MAXREFDES72# is intended to bridge the gap between the Pmod and Arduino-compatible form factors, opening a new audience of developers using Arduino- compatible microcontroller boards. The result is greater accessibility to quality components and faster, easier designs. Maxim offers 15 single function peripheral modules and 13 reference design boards with Pmod connectors, and now each is easily compatible with any Arduino- compatible development board.
Key Advantages include: ease of design and time savings and expanded functionality and versatility, it makes Pmod boards more accessible to a broader range of applications and quickly
connects to Arduino-compatible microcontroller boards for evaluation. "Arduino represents an important and rapidly- expanding ecosystem of ARM developers," said Dominic Pajak, embedded strategist, ARM. "It's great to see high-quality sensor components from Maxim adding to the diversity and choice available to system developers focused on driving innovation around connected devices and services for the Internet of Things."
