RFID with Senses www.ams.com/SL13A SL13A – ISO 15693 Sensor Tag IC - Single-chip RFID data logger - On-chip temperature sensor - Analog input for external sensor - Works with or without battery (semi-passive or fully passive) - 8k-bit EEPROM for data storage We provide innovative analog solutions to the most challenging applications in sensor and sensor interfaces, power management, and wireless. General Description Sensor tags are RFID tags which incorporate sensory functionality in addition to merely providing a unique ID. This allows validating the origin of any object as well as verifying the environmental conditions to which the object has been exposed. Adding sensor functions to the RFID technology opens new horizons for complex applications such as tracking and monitoring of objects and environments in any location. The SL13A is such sensor tag adding a new dimension to the RFID technology. The chip is based on ISO 15693 / NFC-V and incorporates a temperature sensor and an interface to various external sensors. The integrated real-time clock (RTC) time stamps the events. The sensor tag works in fully passive as well as in semi-passive mode (so-called batteryassisted passive or BAP). A battery is used to support autonomous data logging with the on-chip RTC. In passive mode, the reader provides the time stamp, and the energy to the sensors is extracted from the reader’s field (radio waves). Collected and logged data are protected with passwords to preclude manipulation and unauthorized usage of the data. A perpetual protection is available through a permanent lock command which inhibits changing of stored data independent of passwords.
