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.
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.
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 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.
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.
The AS3930 is a single-channel ASK receiver that generates a wake-up signal upon detection of a data signal with a carrier frequency in the range of 110-150 kHz. It can be used to wake-up active tags in RTLS, PKE and other similar tracking and access control systems.
The AS3932 is a 3-channel ASK receiver that generates a wake-up signal upon detection of a data signal with a carrier frequency in the range of 110-150 kHz. It can be used to wake-up active tags in RTLS, PKE and other similar tracking and access control systems.
