Web authentication IC to make NFC authentication scalable

Swiss semiconductor company, EM Microelectronic, announces full volume production of em|linq, the NFC tag authentication IC. em|linq offers to brands the possibility to engage with their customers via NFC and to offer advanced product authentication.

NFC tags are a popular support for consumer engagement, turning any smartphone into a portal for accessing brand content. When the NFC tag content is dynamic, the tags also provide enhanced protection against cloning.

Scalability requires robust, cost-effective products but the authentication component adds cost and complexity typical to smartcards, making the return on investment proposition more difficult. In response, em|linq combines powerful cryptographic mechanisms typically reserved to smartcard products with the convenience and affordability of RFID products, says EM Microelectronic.

It is based on proven, open standards, allowing for full degree of freedom in the implementation of the authentication service. The key management and provisioning. critical for the security architecture, can be handled and fully controlled by the company who implements the solution, regardless of its position in the value chain, whether inlay or label manufacturer, integrator, brand or retailer.

Programming the cryptographic keys into the chips is segregated from programming the URL for the authentication service, providing additional flexibility and security for the system implementation.

The IC also opens up integration possibilities for electronic labels. Its small form factor provides superior mechanical robustness, says EM Electronic. Its power efficiency enables small antenna form factor to enhance communication performance. Electrical characteristics are compatible with most of the antenna designs on the market, reducing the engineering effort.

The authentication engine is built on top of a traditional RFID architecture rather than by simplifying a cumbersome smartcard one. Adding the authentication functionality remains an extension of a traditional RFID use case, with no unnecessary overhead. The tags are produced using the same process flow and with the same quality and cost-effectiveness as the standard RFID products. EM Electronic says its RF performance allows for very small inlay constructions, for ease of integration and to reduce the cost.

em|linq is NFC Type-2 compliant. Optimised cryptographic hardware implementation provides best-in-class web authentication brand protection to consumers’ smartphones, claims EM Electronic, using a dynamically generated HMAC-SHA1 code appended to the URL stored in the NDEF container.

Glucose measuring wristband means non-stop monitoring

At this year’s CES, Quantum Operation will showcase what it claims is the world’s first glucose measuring wristband which enables non-stop monitoring.

The Tokyo-based healthcare IoT start-up explains that the non-invasive glucose monitor uses patented spectrum sensing technology which enables the monitoring sensor to accurately measure glucose in a person’s bloodstream through the skin while being worn around the wrist. The monitor eliminates the need for daily needle uses for diabetic patients, making it more convenient – and pain-free – for users.

The company will also highlight its oxygen saturation (SpO2) measuring sensor that can be worn around the wrist.

The non-invasive 24/7 monitoring relies on Quantum Operation’s core technologies that include spectrometer materials. One of which is designed to emit an optimal spectrum, and another that is highly responsive to target spectra. The wristbands also employ firmware that efficiently extracts targeted data by cancelling noise.

Quantum Operation explains that these technologies can be used to measure all types of vital signs, ranging from heart rate to electrocardiography (ECG). Patients’ conditions can be monitored remotely for convenience and enabling them to continue their normal daily activity as much as possible.

“Until now, sticking a need into your finger or arm has been the only available method for accurately measuring your glucose level,” said CEO Kazuma Kato. “Our wristband will change that, making the painful daily routine unnecessary for all diabetic patients.”

He added: “Our core technologies also enable healthcare businesses to compile accurate big data and provide better solutions for disease control and management. We are very excited to introduce these technologies at CES 2021.”

Quantum Operation is a Tokyo-based, healthcare IoT start up focused on making vital sign measurement as easy and painless as possible. It says its mission is to help people enjoy a healthier and longer lives. Its proprietary technologies are used to provide solutions for both patients and healthcare providers.

Temperature compensated RTC has I2C interface

Claimed to offer the world’s best time accuracy across industrial temperature range at low current consumption, the RV-3032-C7 real time clock (RTC) module has been released by Micro Crystal. The compact RTC module has a custom IC and integrated quartz crystal resonator and sets new standards in size, claims the company. It is half the footprint of a uSOP-8 package, with no additional external components required. It is also claimed to offer the best accuracy (±0.26 s/day at -40 to +85 degrees C operating temperature). Low current consumption (160nA timekeeping mode) and power management capabilities are other features.

The RV-3032-C7 is suitable for applications requiring always-on timekeeping functions, as well as compliance to stringent clock accuracy over time, wide temperature range, and long battery life. Typical examples are smart metering and other similar industrial or consumer applications, such as wearables and IoT devices.

Power management features include a wide supply voltage range (1.2 to 5.5V), automatic backup switch, versatile charge pump and programmable trickle charger. The RTC module can be coupled with a small sized, low capacity, rechargeable battery, or a low cost coin cell power unit which will reduce the overall dimensions and the manufacturing cost of the end product while optimising the life of the battery, advises Micro Crystal.

The RV-3032-C7 includes a quartz-based digital temperature controlled crystal oscillator (DTCXO).

“The design team has applied their 40 years’ of frequency control expertise to develop [the module] . . . . Besides all the standard RTC features, it includes multiple extra functions, like data protection through password, and MHz output frequency, now available for the first time in the market in such a tiny device,” said Hans-Rudolf Gottier, CEO of Micro Crystal.

“The RV-3032-C7 RTC will definitely help engineers in developing next generations of smart products,” he continued. “The availability of a programmable high frequency clock output to drive the central MCU, and access to the high-resolution thermometer, used for accurate thermal compensation and allows setting temperature threshold alarms with interrupt function, will support numerous unique and new applications,” he said.

The RV-3032-C7 is hermetically sealed in a compact reflow solderable DFN ceramic package, measuring 3.2 x 1.5 x 0.8mm. It is RoHS/lead-free-compliant and AEC-Q200 qualified.

MCUs integrate peripherals for sensor-based IoT applications

Sensor-based IoT applications use a combination of analogue functionality and digital control capability to meet cost, size, performance and power parameters for efficiency. In response, Microchip has combined analogue peripherals and multi-voltage operation with inter-peripheral connections in its PIC18-Q41 and AVR DB MCU families. In addition to these attributes for increased system integration and reduced signal acquisition times, they offer the convenience and efficiency of operating in a single design environment, says Microchip.

The introduction bring s easy-to-use analogue capability to cost-effective PIC and AVR MCUs, says Greg Robinson,  so designers can meet the requirements of large-scale IoT systems,” said Greg Robinson, associate vice president of marketing for Microchip’s 8-bit microcontroller business unit. “With a unified, seamless development tool experience, designers can use these MCUs as a single-chip controller, or as an intelligent analogue signal conditioning component in a larger system,” he explained.

The PIC18-Q41 MCU has a configurable operational amplifier and ADC with computation and DACs for signal conditioning in space-constrained sensing and measuring applications such as IoT end nodes and industrial, medical devices, wearables, automotive and lighting systems. It is also well-suited for IoT and large-scale artificial intelligence (AI) at the edge, including predictive maintenance edge nodes in a smart factory, added Microchip. It is offered in compact 14- and 20-pin packages and can be used with Microchip’s 32-bit MCUs and other controllers that require analogue integration.

For mixed-signal IoT systems which often include multiple power domains, the AVR DB MCU integrates true bi-directional level shifters to reduce cost. Typical use examples are automotive, appliances, HVAC and liquid measurement applications. Microchip has added three configurable op amps, a 12-bit differential ADC, 10-bit DAC, three zero cross detectors and Core Independent Peripherals (CIPs) enabling the AVR DB MCU to be used wherever analogue signal conditioning and processing functions are required.

The PIC18-Q41 and AVR DB MCU families are supported by Microchip’s MPLAB X integrated development environment (IDE), its MPLAB Code Configurator (MCC) and the MPLAB Mindi Analog Simulator. MCC is a free software plug-in that provides a graphical interface to configure peripherals and functions specific to an application.

The AVR DB is additionally supported by Atmel START, Atmel Studio and third-party tools such as IAR and the GCC C compiler.

The PIC18F16Q41 Curiosity Nano evaluation kit (EV26Q64A) and the AVR DB Curiosity Nano evaluation kit (EV35L43A) are also available with programming and debugging capabilities.
