RFID-capable memory

13 April 2011 DSP, Micros & Memory

An innovative RFID device from STMicroelectronics allows technical equipment to ‘talk back,’ providing detailed information, such as a full maintenance history, to speed up servicing and simplify record keeping for OEMs and equipment operators.

The new chip, the LRiS64K, combines radio tagging (RFID) circuitry with a 64 Kbit non-volatile EEPROM capable of storing extensive data, such as initial manufacturer details and complete records of repairs or upgrades. Engineers servicing equipment such as medical devices, industrial equipment, auto-motive controllers or avionics modules containing an LRiS64K can access important unit-specific information held directly on the device, by using a standard RFID reader. This onboard storage can eliminate any need to retrieve paper records or access an online database. The unit’s service history can be updated in the device’s memory for access during subsequent inspection or servicing.

The LRiS64K is a long-range 13,56 MHz device, based on the international ISO 15693 and ISO 18000-3 mode 1 standards for RFID devices and capable of co-existing with other devices within range. Its integrated tuning capacitor simplifies connection to an external antenna. The memory can retain data for more than 40 years and withstand more than one million write/erase cycles.
