Wireless Sensor Tags & Interfaces

NFC and UHF RFID sensor tags offer a highly integrated solution for remote sensor data logging. The tags conform to the specifications of the NFC/ISO15693 as well as the UHF RFID standards. Featuring on-chip temperature sensing and the exclusive cool-Log™ technology, these sensor tags enable innovative and cost-sensitive solutions in food and pharmaceutical cold-chain management, industrial process control, remote monitoring and healthcare applications. NFiC™ ICs from ams lower the barriers to NFC integration in electronic devices thanks to their small footprint, high data rate, flexible data transfer modes, fully passive NFC tag emulation and advanced energy harvesting. NFC/HF interface tags are best suited to demanding consumer and industrial applications such as zero-power device configuration and set-up, feature-rich contactless cards for payment and authentication, smart toys and connected cars.

AS39513

The AS39513 is an NFC sensor tag and data logger IC for smart labels which enables more efficient and accurate monitoring of the condition of assets such as food, pharmaceuticals and healthcare products in storage and in transit. The new device is a complete digital sensor with an NFC front end that can easily be integrated into smart labels. A unique ID as well as logged temperature and other data stored in its internal memory can be read by any authorized NFC reader such as a smartphone or tablet. The AS39513 is ideal for applications using thin and flexible batteries but it also supports fully passive operation without a battery using the RF field from an RFID reader as a power source. The AS39513 has a fully integrated temperature sensor with a programmable temperature range (default -20°C to 55°C). The external sensor interface (SEXT) is an analog input and allows the connection of an external sensor. External power can be supplied from a single-cell battery (typically 1.5 V) or a dual-cell battery (typically 3 V).The AS39513 operates in passive mode and harvests energy from a reader’s incoming RF field, supplying external circuitry with a current of up to 3mA. The RFID interface is fully ISO 15693 and NFC-V (T5T) compliant. Configuration and logging data is stored on a configurable 9kbit EEPROM.

AS3955

AS3955 NFC dynamic tag IC is the ultimate solution to easily add NFC functionality to electronic devices, pair them with NFC phones and transfer data. Thanks to a high sensitivity ISO14443A front-end and integrated resonance capacitor, AS3955 offers standalone NFC passive tag functionality in a small footprint. Fast system integration and high speed data transfer are guaranteed by the available SPI and I²C interfaces and by optimized protocols (tunneling mode and extended mode), allowing bidirectional communication between the device microcontroller and an external NFC compliant device or ISO14443A reader device. AS3955 is able to operate fully powered by the RF field, without any external supply. This, combined with an advanced energy harvesting feature, greatly increases battery life time or even allows batteryless designs.

AS3956

AS3956 Dynamic NFC Sensor Tag IC meets industrial-grade quality standards and provides very high reliability in mission-critical applications and in end products with a long operating lifetime. Thanks to a high sensitivity ISO14443A frontend and high integrated resonance capacitor, AS3956 offers standalone NFC passive tag functionality in a small form factor. The AS3956 dynamic tag acts as a contactless bridge between sensors and any NFC reader, such as a smartphone, through a host microcontroller. Fast system integration and high speed data transfer are guaranteed by the available SPI and I²C interfaces and by optimized protocols (Tunneling mode and Extended mode), allowing bidirectional communication between the device microcontroller and an external NFC compliant device or ISO14443A reader device. AS3956 is able to operate fully powered by the RF field, without any external supply. This, combined with an advanced energy harvesting feature, greatly increases battery life time or even allows battery-less designs.

Wireless Sensor Connectivity

The AS3930/32/33 are a family of ultra-low power, low-frequency wake-up receivers which operate in the frequency range 15-150kHz. They include built in correlators to detect 16- or 32-bit programmable wake-up patterns, and offer the choice of 1 or 3 receive channels depending on the requirement to support a fixed or variable orientation between transmitter and receiver. The AS3935 Franklin lightning sensor estimates the distance to the leading edge of a lightning storm. It detects both cloud-to-cloud and cloud-to-ground lightning. It is ideal for consumer grade, battery operated devices for outdoor weather stations, or for leisure activities such as hiking or golf.
