    NXP Announces Ucode 7, a Smaller and Faster Chip 

    NXP-Ucode7-chip-RFID-blog

    NXP Semiconductors has released its latest, highest-performance UHF RFID integrated circuit, which, according to the company, promises to be the highest-functioning EPC Gen 2 UHF RFID IC on the market. The new chip has higher read and write sensitivity, enabling the development of smaller and more versatile tags.

    The Ucode 7’s development began approximately a year ago. During the past few months, manufacturers of RFID tags, readers and printers have been testing the technology. These early efforts, which took place ahead of the public announcement, were intended to ensure that if NXP released this new high-speed, highly sensitive chip, the market was ready to provide the technology (inlays, as well as readers and printers) equipped to use it, says Victor Vega, NXP’s marketing director for RFID products.

    The Ucode 7 chip’s new features include:

    ■Increased read and write sensitivity (meaning the chip requires less power to be read or encoded than previous NXP chips)

    ■Greater backscatter strength (to improve read performance)

    ■faster writing speed

    ■parallel encoding (to provide faster programming when users are encoding a large quantity of tags for products with the same stock-keeping unit)

    ■greater broadband width (to enable improved functionality internationally where the frequency of the reader’s RF signal varies from region to region)

    The chip measures 445 microns by 490 microns (0.018 inch by 0.0l9 inch), and could be smaller. It comes with 128 bits of memory. According to Vega, the new chip’s greater sensitivity and write speed will make it possible for tags to be used in ways in which they have not been previously utilized. For example, he says, it will now be easier for companies to apply very small tags to such items as cosmetics and jewelry.

    Pricing for the chip is expected to be equivalent to that of the G2iL model.

    Gema Puts Multi NFC Chips and Built-in Keyboard into a Single Tag 

    Gema-NFC-tag-multi-chips-built-in-keyboard-rfid-blog1

    U.S.-based startup Gema Touch has introduced a new NFC tag concept that makes it possible to produce a range of new types of interactive experience.

    The new technology involves placing multiple NFC chips on a single tag base that are individually triggered when a consumer places their mobile phone on the base and presses a button.

    “Think of it like an NFC keyboard,” says founder and CEO Joanna Rogerson. “Unlike traditional passive NFC tags that are proximity based, since our tags are triggered by the user’s touch, there is no more threat of cross-talk from having multiple NFC tags in close proximity.”

    “We are using standard NFC chips but store very little data on the tags themselves. Rather we store more of the information on the web and just use the tags as a trigger,” Rogerson adds. “The tags are passive, so no battery. We have literally just broken the circuit on the antenna and placed ICs down the tag. We have a couple of different designs on the buttons, but you can just think of them as a pressure sensitive area that, when pressed, completes the broken circuit on the antenna.”

    Currently, Gema Touch is working with a five chip design but, Rogerson says, “we can increase or decrease that button or IC count no problem”.

    Gema Touch’s design has been patented internationally, including design, utility and manufacturing, and an initial short run of fifty tags is now available on a limited edition basis from NFC specialist Flomio. “Everything else will just be sold through us directly,” says Rogerson.
