Fujitsu Semiconductor developed FRAM products with two frequency bands to serve as chips for high-functionality RFID tags operating in the HF band (13.56 MHz) and UHF band (860 to 960 MHz), which it has offered as the FerVID family since 2004. Today, its products serve a wide range of applications, including chips for data-carrier tags in the factory automation and maintenance sectors that take advantage of FRAM’s fast write speeds and high memory capacity, chips for the medical and pharmaceutical sectors that withstand gamma radiation and electron beams, and chips with serial interfaces for embedded applications.
In addition to these uses, a new need has arisen for larger memory capacities and the ability to connect RFIDs to sensors and microcontrollers as a way to change product operating parameters wirelessly or to wirelessly capture a log of environmental factors during distribution. These features would benefit manufacturing control in automotive and electronics manufacturing, as well as maintenance applications in aircrafts, roadways, buildings, and public works.
Fujitsu Semiconductor has responded to this need with the MB89R112 chip for RFID tags, which includes a serial interface SPI and 9 KB of memory capacity, an amount not found in any competing product for the HF band. The MB89R112 is designed as a near-field passive RFID that complies with the industry standard ISO/IEC 15693. The product will be available in sample quantities beginning in August 2012.
The addition of the MB89R112 to the FerVID Family means that the product line now includes HF-band chips covering a range of capacities from 256 bytes to 9 KB, and UHF-band chips covering a range from 4 KB to 64 KB. In addition, for chips with serial interfaces for embedded applications, the line now includes a 4 KB UHF-band chip and a 9 KB HF-band chip. Together with its varied line of microcontrollers, Fujitsu Semiconductor can meet practically any need.
