ams introduced the AS39513, 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.
It includes an NFC front end, a temperature sensor and an analog interface to an external sensor. Other functions integrated in the IC are a real-time clock, a 10-bit ADC, a configurable data-logging engine, a 9kbit password-protected EEPROM and a serial peripheral interface (SPI) to connect to an external microcontroller. The AS39513 is available as a bumped die or in a chipscale package which is only 0.3mm high. Powered by a single-cell (typically 1.5V) or dual-cell (3V) battery, the AS39513 can store up to 1,020 time-stamped sensor measurements.
