Fujitsu chip for rfid tags offers ‘industry leading’ fram

Fujitsu has added a new device to its FerVID family of chips for rfid tags, which is said to offer 9KB of ferroelectric memory (fram).

Available with either 24pF or 96pF input capacitance, the MB89R112 series is suitable for solutions in factory automation, medical equipment as well as embedded and industrial applications. FerVID products are designed for use as chips in rfid tags operating in the hf band (13.56MHz) and uhf band (860 to 960MHz). The company says that writing 8KB of data takes approximately four seconds, which is six times faster than speeds achieved by e2prom products. By supplementing the hf rfid interface with an additional spi serial interface for microcontroller connectivity, the series is optimised to facilitate the wireless modification of product operating parameters or the logging of environmental factors during distribution.
