The post Limited-Release Energy Harvesting Applications Design Kit appeared first on SemiElectronics.

AVX Corporation, a leading manufacturer and supplier of passive components and interconnect solutions, announces the limited release of its new Energy Harvesting Application Design Kit. The kit features a wide range of low-loss components hand-selected to provide engineers with ideal solutions for energy storage, blocking, IC support, output filtering, and external connections in thermoelectric generators, solar cells, piezoelectric devices, and micro wind turbines, including: MLCCs, supercapacitors, Schottky diodes, inductors, and connectors. It also comes with a booklet that provides users with a brief introduction to energy harvesting and additional information about the components it contains.

“Energy harvesting is finally becoming a practical solution for providing circuit power,” said Eric DeRose, field applications engineer at AVX. “IC and general circuit power needs are trending downwards and reaching levels completely unheard of just a few years ago, the cost of energy harvester sources continues to drop, and the size and efficiency of energy harvesters is dramatically improving, which is allowing engineers to employ smaller, lighter, and more reliable generator sources in their designs.”

Components included in the new Energy Harvesting Application Design Kit include:

  • X5R dielectric capacitors, which offer high volumetric efficiency and are well suited for space-constrained decoupling and filtering applications.
  • X7R dielectric capacitors, which exhibit non-linear temperature variation of capacitance within ±15% from -55°C to +125°C.
  • SCC Series supercapacitors, which offer excellent pulse power handling characteristics resulting from a combination of very high capacitance and very low ESR and can be used by themselves or in conjunction with primary or secondary batteries to achieve extended back-up time, longer battery life, and instantaneous power pulses as needed.
  • SD Series Schottky rectifier diodes, which feature leadless chip packaging technology that eliminates lead frame wire bonds for greater top-bottom symmetry with fewer mounting problems and improved heat transfer and current handling capabilities.
  • LMXN Series (Style B) power inductors, which feature robust, non-shielded ferrite cores.
  • 9286 Series wire-to-wire connectors, which provide maximum wire retention for 18–24AWG solid and stranded wires via an active stainless steel spring contact that eliminates the need for push-button activation and achieves significant cost savings.
  • 9296 Series wire-to-board poke-home connectors, which feature a dual-beam boxed contact system, enable solderless surface-mount attachment to PCBs and provide simple and reliable terminations for 12–28AWG solid and stranded wires.
  • 9175/6/7 wire-to-board STRIPT™ IDC contacts, which provide cost-effective, insulator-less connections for discrete 12–28AWG wires, function just like traditional insulated connectors, and are UL-certified.

AVX’s new, limited-release Energy Harvesting Application Design Kit (part number: KIT-ENERGY HARVEST) is now available and ready to ship.

Highly reliable, industrial-grade dynamic NFC sensor tag IC for mission critical, long-life applications

The post New NFC Sensor Interface for Industrial IoT appeared first on SemiElectronics.

]]>

ams (SIX: AMS), a leading worldwide supplier of high-performance sensor solutions, today released the AS3956, a dynamic NFC tag IC which meets industrial-grade quality standards and provides very high reliability in mission-critical applications and in products with a long operating lifetime.

The AS3956 dynamic tag acts as a contactless bridge between sensors and any NFC reader, such as a smartphone, through a host microcontroller. It supports the NDEF messaging protocol in full compliance with NFC Forum recommendations, guaranteeing interoperability with any NFC phones, including Apple® iOS devices

In designing the robust AS3956, ams drew on close interaction with customers that manufacture products for industrial applications and the Internet of Things (IoT). Intensive testing in real-world applications has validated the performance and reliability of the chip in a wide range of demanding operating conditions.

Unlike the consumer-grade dynamic NFC tags on the market today, the AS3956 is ideally suited to:

  • industrial and Internet of Things (IoT) applications exposed to harsh operating conditions, including extreme temperatures ranging from -40°C to 125°C;
  • products requiring an extended operating lifetime, such as HVAC equipment, hearing aids, and wireless sensors for infrastructure such as roads, bridges and utilities. The AS3956’s internal EEPROM memory is rated for a minimum 100,000 program/erase cycles, and offers 10 years’ data retention at 125°C;
  • mission-critical products that require a zero failure rate;

The AS3956 includes various features that give the designer flexibility in implementing NFC-based applications. These include the provision of both an I2C and an SPI interface to a host microcontroller, and a wide supply voltage range of 1.65V-5.5V.

In basic operation, the AS3956 acts as a stand-alone Type 2 tag conforming to the NFC Forum standards and supporting NFC communication with a reader. In addition, either of two data-transfer modes for host controller communication can be selected:

  • Extended Mode, a self-timed data transfer mechanism using standard Type 2 tag commands, thus minimizing software overhead on the host controller
  • Tunneling Mode to implement ISO14443A Level 4 PICC emulation in line with EMVCo requirements or custom protocols

The AS3956 includes an energy-harvesting capability, drawing energy from the incoming RF field generated by an NFC reader, and supplying up to 5mA to an external device. Energy harvesting is particularly useful as a cost effective, small footprint alternative to standard wireless charging, to extend battery lifetime in biometric smart cards, or to implement fully passive wireless sensing solutions, as required for example in smart insulin pens.

“Previous generations of general purpose NFC dynamic tags have not offered the reliability and flexibility that many applications require. The AS3956 offers far superior lifetime performance. The rigorous quality processes and numerous validation tests put in place by ams will give customers confidence that the AS3956 can cope with operation in harsh or extreme conditions and still maintain unimpaired RF, interface and memory functions,” said Giancarlo Cutrignelli, Head of Marketing for Wireless Sensor Nodes at ams.

ams provides the AS3956 in a miniature chip-scale package (CSP) just 0.3mm high, and with a 1.8mm x 1.4mm footprint as well as in a 3mm x 3mm MLPD package. It is available for sampling now. Unit pricing is $0.53 in an order quantity of 1,000 units.

A demonstration kit is available from the ams ICdirect online store. For sample requests or for more technical information, go to www.ams.com/Sensor-Tags/AS3956.
