Atmel Debuts Multifunctional 1k-bit R/W RFID UHF IDIC TAGIDU ATA5590

9/14/2004 - Atmel® Corporation (Nasdaq: ATML) announced the availability of its new UHF RFID IDIC® ATA5590, named TAGIDU, that serves a very broad spectrum of long-range RF Identification applications. TAGIDU can be used in a frequency range of 800 MHz to 1 GHz and is suited for worldwide use. Its flexibility and the outstandingly low power consumption enable to achieve a unique read/write performance with extended distances up to 10 meters. The ATA5590 is a result of the research and development of the European-funded project Palomar, and also of Atmel's long-term research in the area of RFID. TAGIDU uses Atmel's unique and flexible UHF platform concept, named AIDU.

The need for RFID is growing substantially due to its increased performance and enhanced functionality. Compared with bar codes, RFID provides extended read/write distances, line-of-sight is not necessary, and data can be changed whenever needed. Long-range UHF provides logistic advantages especially for supply-chain applications, resulting in larger volumes of goods to be identified.

The TAGIDU IC ATA5590 is designed for intelligent passive tags and labels. Its features make the device well-suited to match the needs of supply-chain management and logistic applications. TAGIDU addresses the GTAGÔ requirements and is able to carry EPC data structures. The innovative link mechanism, along with the device's extremely low power consumption (typically 10 µW), enable maximum operation distances in several application environments. Read/write distances of up to 10 m with 4 W EIRP can be achieved. The device also features simultaneous operation of multiple tags in the field of one reader antenna (anti-collision function, up to 460 tags per second), and 1024 bits of user memory plus 320 bits of system memory.

The device's forward link enables the user to choose either of two modulation schemes: state-of-the-art ASK or the new DSBM (Double SideBand Modulation, a quasi modified PSK coding) modulation, thus selecting the best combination of operation range, bit rate and secure link mechanism.

"No matter which application, which standard, which country, or which specific requirements, our new TAGIDU device fits in almost any application environment without complex adaptation. The ATA5590 is not pre-configured before use, all settings depend on the reader's protocol. Such a flexible and easy-to-use UHF solution has not been available on the market up to now. We are also excited to announce that further AIDU-compatible products are in preparation,” said Michael Fislage, Atmel's RFID Marketing Manager.

Atmel, a pioneer in the RFID area and member of EPCglobal, provided the industry’s first read-only RFID ICs in the late 1980’s. Since 1995, Atmel has also been offering the world’s most flexible read/write RFID ICs. Today, Atmel is a key player for low-frequency-based 125 kHz RFID ICs for access control systems. The portfolio also includes ICs addressing the 13.56 MHz, UHF and Microwave frequency range.

Samples of the new TAGIDU RF IDIC ATA5590 as die-on-wafer or in TSSOP10 packages (for engineering purposes only) are available now. Pricing starts at US$0.46 (10 k).
