Fujitsu Semiconductor America has announced a FRAM-based device that the company said offers the industry's highest memory capacity for a high-frequency RFID IC. A member of the Fujitsu FerVID family, the MB89R112 uses FRAM memory for fast write speeds and high-frequency rewriting capabilities, providing excellent radiation tolerance and low-power operation, noted the company.

The device includes 9KB of FRAM, with a full 8KB available as user memory. Memory is structured as 256 blocks of 32B per block, permitting read and write access to the entire 8KB region defined in ISO/IEC15693. Writing 8KB of data takes about four seconds, a high-speed operation six times faster than products using EEPROM, stated Fujitsu.

The MB89R112 operates at 13.5MHz 7kHz and assures data retention for up to 10 years. In addition to its wireless HF interface, the dual-interface MB89R112 incorporates a wired serial interface (SPI) for microcontroller connectivity, the company added.

Supplying more available data on RFID tags enables efficient use in various applications, and the combined features of the MB89R112 create new options for RFID use in embedded and industrial designs. Examples include facilitating wireless modification of product operating parameters, logging environmental readings for logistics, detecting equipment errors, modifying electronic displays, altering sensor threshold values and changing firmware settings. Capabilities like these can enhance production control in automotive and electronics manufacturing. They can also help with maintenance applications in aviation, road building, construction and civil engineering.

The MB89F112 is available in sample quantities.
