New IC Design Promises to Enable Trillions of RFID Tags

Impinj calls its new integrated circuit process its most significant innovation since the release of its Monza chip in 2005; the new IC will enable a smaller, faster and more effective series of RFID chips that could fuel major advancement in the UHF RAIN RFID industry.

Internet of Things (IoT) technology company Impinj has developed new technologies for integrated circuits (ICs) that will lead to a series of smaller, more functional RAIN RFID chips. Ultimately, the company reports, the new chips will enable its technology partners to make tags and labels featuring significantly improved read distance, reliability and speed.

The new offerings will result in a series of chips known as the Impinj M700 endpoint IC series, the company indicates. The firm says it is working with a select group of RFID technology partners to test, validate and ensure the availability of RFID inlays containing the new ICs as new products are announced. Impinj will demonstrate the chips' functionality at the RFID Journal LIVE! conference and exhibition, taking place next week in Phoenix, Ariz.

"What we're introducing are technology innovations upon which a new series of Impinj M700 chips will be developed and released," says Jeff Dossett, Impinj's executive VP, sales and marketing. The new design enables significant shrinking of the size of the ICs, which Dossett says will be able to accomplish more than predecessor models.

The new process, leveraging recent semiconductor advancements, follows Moore's Law—the theory that integrated circuit size reduces by half every two years. Impinj has been able to shrink the logic area of the chip, Dossett explains, enabling it to deliver a next-generation IC with better capabilities, and to do so in a smaller form factor.

This technology shift is the culmination of a decade of innovation, Dossett says, and represents Impinj's most significant announcement since its first EPC UHF RFID product, the Monza chip, was released in 2005. The M700 series will be the first built using this new design. The company expects the new ICs to enable small, effective and lower-cost tags that could be applied to everyday items, including small, inexpensive consumer goods, for the purposes of brand authentication, loss prevention or other applications.
