The FMM22L16-55-TG from Cypress is a 4-Mbit non-volatile Ferroelectric RAM (F-RAM). Organized as 256K x 16, this device features a high-speed parallel interface and operates from a single 2.7V to 3.6V supply. With a fast 55 ns access time and an industrial temperature range of -40°C to +85°C, it is engineered for applications requiring frequent and fast writes with high endurance. Housed in a compact TSOP-44 package, it is ideal for data logging, industrial control systems, and medical devices where reliable, non-volatile storage is critical.

Features
