FM 24C04B-G – FRAM, 4 Kb (512 x 8), 4,5 … 5,5 V, SO-8

4-Kbit Serial (I2C) FRAM, 512×8, 5V, 1MHz, SO8, The FM24C04B is a 4-Kbit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes similar to a RAM. It provides reliable data retention for 151 years while eliminating the complexities, overhead, and system-level reliability problems caused by EEPROM and other nonvolatile memories.
