Smartrac steps up security with NFC PRO tags

Fri, Sep 06, 2019

RFID technology and IoT specialist, Smartrac has launched the Pro series of NFC tags and inlays. The Circus Pro NFC tag, equipped with NXP’s NTAG 424 DNA IC, will be the first member of the new product series optimised for highly secure product authentication.

By embedding Circus, or subsequent Pro inlays or tags, into physical products, customers can turn products into secure digital platforms. Smartrac says they can deliver value during the product lifetime, from point of manufacture, through the supply chain, distribution channels, point of sales, customer use, to reselling and recycling. Secure product authentication protects against counterfeiting and diversions and also provide exclusive content and rewards for consumer engagement and customer loyalty programs.

“As the number of connected objects is expected to reach a record 40 billion by 2022, organisations of all sizes are seeking not just feature-rich, connectivity solutions but ones that can securely protect their brand, their products, and their customers,” said Philippe Dubois, vice president and general manager of IoT Security, Smart Mobility and Retail at NXP.

Smartrac’s Circus Pro inlays and tags with NXP’s NTAG 424 DNA ICs work with all NFC-enabled devices and support real-time tag and message authentication based on AES-128 encryption on attack-resistant certified silicon. The secure unique NFC (SUN) authentication enables authentic, integrity protected and confidential data exchanges between tags and servers. This high-end security IC offers enhanced privacy features and a sensitive on-chip data storage, says Smartrac, protected by a sophisticated three-pass mutual authentication scheme.

Future Pro features and options will include different security layers, allowing customers to enable secure product authentication for a range of applications. Smartrac will soon introduce further Pro versions of its popular NFC inlays and tags such as Bullseye and Midas, the company confirmed.

NFC-based secure product authentication can be achieved through a choice of verification services to comply with individual customer requirements. The secret keys cannot be copied or tampered and physical product authenticity can be proven once the Pro inlays and tags are irremovably embedded into or attached to the physical product.

Smartrac’s Circus Pro NFC inlays and tags with NTAG 424 DNA will become available in large quantities in Q3 2019 as wet inlays and the Circus Pro Flex wet inlays, which come with an additional protective layer for the IC and antenna connection area for enhanced durability.

Charge e-bikes’ batteries wirelessly says Würth Elektronik

Thu, Sep 05, 2019

Developers of charging devices and charging stations can provide wireless battery charging for e-bikes and small electrical vehicles, says Würth Elektronik, as it unveils its support for developers to implement individual charging concepts.

Besides providing expert know-how in the form of training seminars or on-the-spot development support, Würth Elektronik has also designed many development kits that help manufacturers to bring their products to the market more swiftly.

“When a battery pack is charged by cable, you have to reckon with between 2,000 and 5,000 plug cycles over the battery’s life cycle. Especially because users generally recharge batteries that are not fully discharged on the go to ensure mobility, in many cases the charging sockets and plugs wear out faster than the actual batteries themselves,” explains Sven Lerche, business development manager New Mobility at Würth Elektronik eiSos. “Repairing charging sockets or charging devices is rarely an economically viable option, and wireless charging is an extremely attractive alternative. Then you’ve also got a number of other advantages like the high convenience factor, the fully enclosed design, and the insensitivity to environmental factors.”

Würth Elektronik explodes three popular misconceptions about wireless power: inefficiency, safety and expense.

When the recommended position of the device is even only roughly adhered to – an aspect that can be enhanced by the mechanical design – efficiency is about 95 per cent, says the company. It adds that the fear of electric shock or suffering burns is also unfounded because the industrial standards prescribe an automatic switch-off device that cuts in as soon as a foreign body gets between the charging coil and the receiver coil. The technical effort required for this is minimal, Würth Elektronik confirms.

As for expense, the plug and socket are replaced by wireless power coils and a slightly more sophisticated electronics, which ultimately can even result in a cost-neutral solution, insists the company.

Würth Elektronik eiSos Group manufactures electronic and electromechanical components and is one of the largest European manufacturers of passive components, with production sites in Europe, Asia and North America.

Wide-angle thermal MEMS sensor contactless offers Omron’s widest field of view

Wed, Sep 04, 2019

Omron Electronic Components Business Europe has added a wide angle 32 x 32 element version of its D6T MEMS thermal sensor. It offers the widest field of view that Omron has ever delivered, says the company.

The Omron D6T-32L-01A can view across 90.0 x 90.0 degrees, enabling it to encompass a wide area, such as a whole room, from a single point. The sensor offers contactless measurement of temperatures of 0 to 200 degrees C in ambient temperatures of -10 to + 70 degrees C.

Omron D6T MEMS thermal sensors are based on an IR sensor which measures the surface temperature of objects without touching them using a thermopile element that absorbs radiated energy from the target object. They incorporate a MEMS thermopile, custom designed sensor ASIC and signal processing microprocessor and algorithm in a tiny package. According to Omron, the D6T offers the highest signal-to-noise ratio (SNR) in the industry. It converts the sensor signal to a digital temperature output giving a straightforward interface to a microcontroller. The design of the D6T, which measures only 14 x 8 x 8.93mm for the largest 32 x 32 element version, makes it well-suited to temperature detection in a range of IoT and other embedded applications.

The D6T-32L is one of three D6T variants by Omron, joining the 1×8 D6T-8L-09H and the 4×4 D6T-44L-06H, offering 54.5 x 5.5 and 44.2 by 45.7 degrees respectively. These two devices offer contactless temperature measurement between 5.0 to 200 degrees C at ambient temperatures of 5.0 to 45 degrees C.

The D6T sensors can be used to detect abnormal temperatures in industrial equipment on the production line to monitoring of food and other temperatures in the kitchen. This can save costs, allowing preventative maintenance to be undertaken in a timely manner, points out Omron, and can even save lives. They can also detect the presence and location of people in a space accurately and reliably.

PCIe Gen4 NVMe SSD controllers are low power for edge computing

Mon, Aug 12, 2019

Claimed to offer unparalleled performance-power benefits, the PCIe Gen4 NVMe solid state drive (SSD) controller is designed for edge computing and cloud data centre applications.

The SSD controllers are designed to meet the need for lower power and higher performance in next-generation data centres and edge devices as artificial intelligence (AI) and 5G gain momentum, explains Marvell Semiconductor. The SSD controller is claimed to be the industry’s lowest power PCIe Gen4 NVMe solid state drive (SSD) controller, leveraging the company’s system-on-chip (SoC) design expertise and storage IP distributed data.

Nigel Alvares, vice president of marketing for the flash business unit at Marvell Semiconductor, believes the PCIe Gen4 NVMe SSD controllers are “demonstrating Marvell’s leadership in storage, delivering the industry’s first four-channel PCIe Gen4 NVMe SSD controllers with the industry’s lowest power consumption that will help revolutionise SSD solutions for the data economy.”

The 88SS1321, 88SS1322 and 88SS1323 are believed to be the industry’s first PCIe Gen4 DRAM and DRAM-less SSD controllers to be fabricated on a 12nm process. With support covering all existing and emerging m.2 (22110 to 2230), BGA, EDSFF and U.2 SSD form factors, the controller family is suitable for cloud data centre server compute storage, enterprise boot drives, PC client storage and gaming storage as well as emerging industrial and edge device applications.

The PCIe Gen4 NVMe SSD controllers will enable next-generation 3D and QLC NAND devices that maximise cost efficiency and reduce total cost of ownership, adds Marvell. The compact, DRAM-less controller architecture allows for a stand-alone SSD controller and NAND unit to be mounted side-by-side on a single-sided, compact m.2230 form factor SSD. The resulting space saving leaves more room to house battery packs compared with m.2280 SSDs and also provides better performance compared to PCIe Gen 3×4 SSDs and lower power consumption compared to eight NAND channel controller-based SSDs, says Marvell.

Marvell’s revolutionary SSD controllers are available for sampling today.
