AS39513 NFC Sensor Tag IC

NFC-V sensor tag and data logger IC


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.
