STMicroelectronics releases RFID memory

Janine Love, Editor, EE Times' Memory Designline -- EDN, January 7, 2011

The LRiS64K 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 LRiS64K chip combines radio frequency identifation (RFID) circuitry with a 64-Kbit non-volatile EEPROM capable of storing data, such as initial manufacturer details and complete records of repairs or upgrades.

Key features of the LRiS64K:

• 64-bit Unique Identifier (UID)
• 64-Kbit User Memory
• 13.56MHz carrier frequency, ISO15693 standard
• Multi-password protection
• 53-kbit/s wireless data rate
• 5.75ms typical memory programming time

The LRiS64K is a long-range 13.56MHz 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.

Availability
The LRiS64K is starting in mass production now. It is available in bumped and sawn wafer suitable for Direct Chip Attachment (DCA).
