The FM28V202A is a 128 K × 16 nonvolatile memory that reads and writes similar to a standard SRAM. A ferroelectric random access memory or F-RAM is nonvolatile， which means that data is retained after power is removed. It provides data retention for over 151 years while eliminating the reliability concerns， functional disadvantages， and system design complexities of battery-backed SRAM （BBSRAM）。 Fast write timing and high write endurance make the F-RAM superior to other types of memory. The FM28V202A operation is similar to that of other RAM devices and therefore， it can be used as a drop-in replacement for a standard SRAM in a system. Read cycles may be triggered by CE or simply by changing the address and write cycles may be triggered by CE or WE. The F-RAM memory is nonvolatile due to its unique ferroelectric memory process. These features make the FM28V202A ideal for nonvolatile memory applications requiring frequent or rapid writes. The device is available in a 400-mil， 44-pin TSOP-II surface mount package. Device specifications are guaranteed over the industrial temperature range –40 °C to +85 °C. For a complete list of related documentation， click here.
