STMicroelectronics has introduced a low cost 'long range' contactless memory intended for high volume applications in supply chain management, e-commerce and access control.

Complying with the ISO 15693 standard for 13.56MHz contactless products, the LRI64 is a 64-bit, One Time Programmable (OTP) user memory with an additional 64-bit read-only Unique Identification number (UID). It is organized as 16 blocks of 8 bits, of which the first eight rows contain the 64 read-only UID bits. Under certain conditions, the company can make part of this UID number programmable by the end user.

The LRI64 enters its operational mode only when the UID is completely and properly programmed. It includes an internal tuning capacitor and KILL command, and supports the AFI register that allows operation of the anti-collision sequence.

A 56-bit space remains available for the user as a write once, read many area (WORM), and its 128-bits total memory size allows the product to support and store a 96 EPC (Electronic Product Code) data coding on demand. Its nonvolatile memory technology features a 40-year data retention to support long life application requirements.

Samples of LRI64 are available, with volume production expected by the end of May 2004. US pricing for the LRI64 is 10 cents in quantities of 1 million units. Both LRI64 and LRI512 can be delivered in various formats including thin un-sawn wafers, sawn and bumped wafers, or as inlays.
