Introduced as the first nonvolatile memory to feature unlimited endurance, the 256-Kb, 3V FM18L08 ferroelectric random access memory (FRAM) offers an unlimited number of read and write cycles—FM18L08's underlying FRAM technology guarantees an endurance spec of at least 10¹⁶ read/write cycles.
Each memory location can be accessed one million times per second for more than 300 years without loss of data retention. Capable of replacing battery-backed SRAM or other nonvolatile memory, FM18L08 32Kx8 FRAM has an industry-standard SRAM and EEPROM pin out, operates from a 2.7V-3.6V supply, draws 15 mA at a 70-ns access time, and has an operating temperature range of -40°C to 85°C. Price of the 28-pin SOPs or DIPs starts at $4.50 each/10K.
