Called as MB89R112, the new FRAM-embedded LSI is the latest of its FerVID family, which has a built-in FRAM memory circuitry for fast write and high-frequency rewriting capabilities, providing excellent radiation tolerance and low-power operation.
The device includes 9 kilobytes (KB) of FRAM, with a full 8 KB available as user memory. Memory is structured as 256 blocks of 32 bytes per block, permitting read and write access to the entire 8 KB region defined in ISO/IEC15693.
Writing 8 KB of data takes about four seconds, six times faster than products using EEPROM.
A short for ferro-electric random access memory, FRAM is a sort of non-volatile memory chips that can store data even when power is off, combining the advantages of ROM and RAM chips. It gains over flash memory chips in read and write speed, but runs short storage capacity.
The MB89R112 operates at 13.5 MHz +/- 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.
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.
Cases in point 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 MB89R112 meets the market need for higher capacity memory with an RFID interface to sensors and microcontrollers," said Tong Swan Pang, senior manager of marketing at Fujitsu Semiconductor America. "The dual-interface FRAM-based RFID enables customers to log, store, modify and exchange data flexibly between wireless RFIDs and wired embedded systems."
