Coupler and Tag Pair from STMicroelectronics Ease RF Tagging Solutions.Business & Technology Editors GENEVA--(BUSINESS WIRE)--Oct. 8, 2002 Low-cost design opens the way for wider use of RF tags and embedded readers STMicroelectronics (NYSE NYSE See: New York Stock Exchange : STM (Scanning Tunneling Microscope) A microscope that can image down to the atomic level. An STM uses a piezoelectric tube with a tiny sharp tip at the end that is moved within nanometers of the object being sampled. ) has introduced a pair of devices that can be used to build low-cost, short-range radio-frequency (RF) tagging and identification systems. The parts, an RF reader interface and a contactless non-volatile memory Refers to memory chips that hold their content without power being applied. It may refer to chips that are not changeable, such as ROMs and PROMs, or to chips that can be rewritten many times such as flash memory. are designed for use over short distances, particularly where the reader is embedded in another device. Applications include identifying electronic consumables, for example printer or toner cartridges, magnetic tapes or external batteries. Other applications include access control. Both chips include an `anti-collision' mechanism that allows them to deal with the presence of many tags within the reader's range. The chips also have an `anti-clone' function, developed at France Telecom, which allows a tag to be authenticated. These features enable users to design a reader/tag system with authentication, offering a high level of security at a low cost. The chips can be used as a pair or with other RF tagging and identification solutions. CRX CRX Civic Renaissance Model X (Honda automobile model) CRX Cone-Rod Homeobox-Containing Gene CRX Civic Renaissance Experimental (Honda) 14 RF reader chip The CRX14 is a short-range contactless reader that conforms to the ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. 14443 type B standard and is controlled using the two-wire I(2)C bus. It generates a signal on an external antenna that provides power and transmits data to an RF tag. The received data are captured by the tag, which is powered by the energy transmitted by the reader. The reader chip is designed to be connected to a digital host that manages all the communications protocol Hardware and software standards that govern data transmission between computers. The term "protocol" is very generic and is used for hundreds of different communications methods. A protocol may define the packet structure of the data transmitted or the control commands that manage the in both directions through the I(2)C serial bus. The device is available in an SO16N package. SRIX4K short-range contactless memory chip The SRIX4K is a contactless memory that complements the CRX14 reader. It includes 4096 bits of non-volatile memory, and supports the anti-collision and anti-cloning functions that the CRX14 also implements. The memory is built in STMicroelectronics' CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. technology, and is organized in three areas. The first is a re-settable OTP (1) (One Time Programmable) Refers to programming content or logic into chips such as EPROMs and EEPROMs, which cannot be reversed. See antifuse. (2) (One Time P in which bits can only be switched from 1 to 0. The second area provides two 32-bit binary counters. The last area is the main non-volatile memory, which is accessible in 32-bit blocks. STMicroelectronics' high-endurance CMOS technology means the SRIX4K will allow at least 1 million program-erase/write cycles and retain data for at least 10 years. The SRIX4K is designed for short-range applications such as consumable products identification, anti-counterfeiting or ticketing. The device is available in various formats including un-sawn wafers, sawn and bumped wafers or as inlays.
