ams offers 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:
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:
