Impinj and Texas Instruments Announce RFID Gen 2 Supply Agreement

Impinj’s Silicon Chips Enable TI’s Ultra-high Frequency (UHF) EPC Gen 2 Products

SEATTLE, Wash., November 29, 2005 -- Impinj, Inc., the fabless semiconductor company whose patented Self-Adaptive Silicon® technology enables its two business lines: semiconductor intellectual property and high performance radio frequency identification (RFID) products, and Texas Instruments Incorporated (TI) (NYSE: TXN), a leading provider of RFID chips, inlays and straps, today announced a supply agreement under which Impinj will provide its Monza™ RFID Generation 2 (Gen 2) chips for inclusion in TI’s initial production of RFID inlay and strap products.

As part of its Gen 2 product offering, TI is using Monza chips from Impinj for its manufacturing of Gen 2 inlays and straps that label converter companies are incorporating into finished RFID tags for use by consumer goods manufacturers in the global retail supply chain. Part of Impinj’s GrandPrix solution for robust RFID systems, Monza is the world’s first tag chip certified as compliant with the Gen 2 standard promulgated by EPCglobal Inc™, the industry consortium established to promote RFID in the global supply chain.

“We are very pleased that our cooperation with TI has resulted in this supply agreement,” said Dr. William Colleran, president and CEO, Impinj. “With this announcement, we add to the already impressive list of strap and inlay customers who have selected Impinj’s Monza chips as their choice for high volume Gen 2 solutions.”

“This agreement with Impinj, in combination with TI’s development of Gen 2 inlay and strap products, has accelerated our global retail supply chain customers’ transition to this new standard,” said Tony Sabetti, UHF/Retail Supply Chain director, Texas Instruments RFid Systems.

Impinj’s Monza Gen 2 chips provide all of the benefits promised by the Gen 2 protocol, including improved tag readability and throughput, compliance with global spectral regulations, 96-bit EPC identification codes and enhanced security, privacy and robustness. Compared to legacy Gen 1 chips, Monza chips feature superior read and write range, high-speed field rewritability and orientation insensitivity when used in a dual antenna configuration. In keeping with Impinj’s high quality standards, Monza chips are 100% factory tested and exhibit excellent RF impedance and ESD insensitivity, characteristics for ensuring superior inlay manufacturability in accordance with TI’s rigorous standards for quality and performance.
