DESCRIPTION
The WM710xx is a RFID transponder IC with nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory, or F-RAM, is nonvolatile and performs reads and writes like a RAM. It provides reliable data retention for 20 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories.
