Brazilian Chip Maker Announces EPC UHF Chip
CEITEC expects that tags manufactured with the new IC, which has 1 kilobit of memory, will become available in mid-2012.
Oct 18, 2011—Having recently completed testing of its new EPC Gen 2 passive RFID chip, the CTC 13000, CEITEC—a government-funded Brazilian semiconductor firm—estimates that tags manufactured with its new chip will become commercially available in June 2012, according to Marcelo Soares Lubaszewski, CEITEC's design and institutional relations superintendent.
Hewlett-Packard (HP) RFID Center of Excellence (CoE), a research and development facility in Sao Paulo, Brazil, carried out the tests, which followed a two-year collaboration between CEITEC and the HP RFID Center of Excellence to develop the chip. According to Alexandre Quinze, CoE's senior director of research, development and IT, the ultrahigh-frequency (UHF) chip was designed to offer the same functionality as other EPC UHF chips currently on the market, and to transmit at the 902.250 MHz, 915.250 MHz and 927.250 MHz bands, in order to meet the demand for such chips in Brazil and elsewhere worldwide.
"CoE has been working closely with CEITEC for the last two years to cooperate and help them develop the chip," Quinze states. "This is an extensive technical joint effort."
The chip contains 1 kilobit of memory, with 512 bits available as user memory and 240 bits dedicated to the Electronic Product Code (EPC) number. The read range is approximately 4 meters (13 feet) for reading or writing to the tag, Lubaszewski says, while the operational temperature range is -40 degrees Celsius to +85 degrees Celsius (-40 degrees Fahrenheit to +185 degrees Fahrenheit).
