ams revealed new sensor-enabled RFID tags for medical, automotive safety and other applications where temperature, physiological or environmental data is required. The new devices – the SL13A and SL900A – enable simple, low-cost implementation of wireless data-logging applications.
The SL13A is an ISO15693-compliant tag for use with near field communications (NFC-V) and high-frequency radio-frequency identification (HF RFID) readers. The SL900A is an EPC Gen 2 Class 3 tag for use with RFID readers.
The devices include an onboard temperature sensor, an interface to an external sensor, and can operate in passive (battery-less) mode. In this mode, the tag harvests energy from a reader’s broadcast, using the power to read the temperature or data from an external sensor, and transmits the information back to the reader together with a unique ID. The data is time-stamped by the reader.
The SL13A and SL900A can be powered by a single-cell or 3 V battery. In battery-assisted passive (BAP) mode, the tag’s onboard real-time clock is enabled, and can be used to trigger periodic sensor readings. Up to 762 (SL13A) or 841 (SL900A) time-stamped events may be saved in the on-chip EEPROM, from where they may be read when the device is in range of a reader.
The combination of a sensor interface, NFC compatibility and support for passive mode offers designers the opportunity to invent new kinds of wireless data-logging applications, or to find better ways to implement existing data-logging systems. Applications as diverse as patient monitoring, building control and automotive safety can benefit from the ability to read biomedical, humidity or pressure measurements via the SL13A using harvested energy from an NFC reader such as an Android smartphone or tablet.
Both the SL13A and SL900A feature a serial peripheral interface for connection to a microcontroller. They can operate from a power supply ranging from 1,2 V to 3,6 V. The tags provide for very long battery life, drawing a typical 1,6 μA in standby mode with the real-time clock running. The onboard temperature sensor is accurate to up to 0,5%.
