The FM18W08-SGTR is a 256-Kbit (32 K × 8) parallel ferroelectric random access memory (F-RAM) in a 28-pin SOIC package, offering nonvolatile data retention for up to 151 years and endurance of 100 trillion (10^14) read/write cycles. It operates from 2.7 V to 5.5 V across -40°C to +85°C, with 70-ns access and 130-ns cycle times for fast SRAM-like performance.
