Overview
The FM28V100-TG is a 1-Mbit (128K × 8) ferroelectric random access memory (F-RAM) produced by Infineon Technologies. This nonvolatile memory device operates similarly to a standard SRAM, allowing for read and write operations without the need for additional power to retain data. The FM28V100-TG is designed to be a drop-in replacement for standard asynchronous SRAMs, eliminating the reliability concerns and system design complexities associated with battery-backed SRAM (BBSRAM). It offers fast write timing and high write endurance, making it ideal for applications requiring frequent or rapid writes.
