Atmel Announces Extra-Small Transponder Identification Chip.Business Editors/High-Tech Writers HEILBRONN, Germany--(BUSINESS WIRE)--Oct. 16, 2001 Atmel(R) Corporation (Nasdaq:ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) announced today the new 330-bit read/write transponder A receiver/transmitter on a communications satellite. It receives a microwave signal from earth (uplink), amplifies it and retransmits it back to earth at a different frequency (downlink). A satellite has several transponders. IC T5557 which is based on Atmel's standard IDIC IDIC Infinite Diversity in Infinite Combination IDIC International Diving Instructor Corporation IDIC Intelligence Division Indication Center IDIC Infinite Diversity in Infinite Combinations (R) e5551. The small chip size (less than 1 square millimeter) enables a broad range of assembly options, the device can be built specifically into all transponder packages. Applications include access control (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. cards) as well as laundry-, waste or animal identification systems. The T5557 is designed for batteryless identification systems with a 120 to 134-kHz magnetic field. The IDIC is the industry's most universal read-/write device regarding modulation modes and data rates. Modulation modes include Manchester, PSK (1) See preshared keys. (2) (Phase Shift Keying) A simple digital modulation technique that uses two different phase angles for 0 and 1. Quadrature PSK (QPSK) uses four phase shifts for each two bits of input. See phase modulation and DPSK. , FSK (Frequency Shift Keying) A simple digital modulation technique that uses two frequencies for 0 and 1. See frequency modulation. , NRZ (Non-Return-to-Zero) A data transmission method in which the 0s and 1s are represented by different polarities, typically positive for 0 and negative for 1. See NRZI. NRZ - Non Return to Zero (see footnote) and Biphase coding. Data rates can be configured in a range between Rf/16 and Rf/128 to optimize the application according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. distance and data transfer requirements. These features enable to address the ISO11784/, 11785/ and FDX-B standards. The read/write chip offers a 330-bit memory, consisting of 224-bit user memory (7 x 32 bits), 64-bit unique tag-ID (traceability information included) and a 32-bit configuration block. The user memory can be protected against unauthorized access via password. This new T5557 provides low power consumption for extended read/ write operating distance (up to 40%, depending on the antenna circuit design), increased programming speed (5.7 ms per block), improved light protection against UV light, and improved temperature resistance (24 h at 250 degrees C) for proper data retention in high-temperature applications such as automotive paint lines. Both the improved light protection and the on-chip 75-pF capacitor help to reduce assembly costs, as less production steps are necessary. "With the extra-small T5557, we proudly announce the newest member of our broad family of RF identification ICs," said Torsten Mann, marketing director for Automotive and Control products at Atmel Wireless & Microcontrollers division. "The improved performance and the reduced chip size meet today's demands for higher volume production," Mann concluded. Samples of the T5557 are available now. Pricing for the T5557 starts at $0.31 (10 k). To support the system designer, Atmel provides demo boards with updated demo software and design guides including application guides.
