Fujitsu launches new chip for High-Frequency RFID Tags with Industry-Leading 9 KB FRAM


Fujitsu today announced a new arrival to its FerVID family of chips for RFID tags. As with all members of the FerVID family, the MB89R112 series uses ferroelectric memory (FRAM) for fast write speeds, high-frequency rewritability, radiation tolerance and low-power operation. The new MB89R112 series includes 9 KB of FRAM, the greatest density available in an RFID chip operating in the HF band as defined in ISO/IEC 15693. Of this 9 KB, 8 KB is provided as user memory, enabling access by read/write operations to the entire 8 KB region as defined in ISO/IEC 15693.

The series will be offered in two variants, with 24pF and 96pF input capacitance. Writing 8 KB of data takes approximately four seconds, a high-speed operation that is six times faster than speeds achieved by E2PROM products. Application examples include logging environmental readings for logistics, detecting equipment errors, modifying electronic displays, altering sensor threshold values, changing firmware settings, plus many other novel and innovative applications that were previously unworkable.
