General Description
The FM28V020 is a 32K x 8 nonvolatile memory that
reads and writes like 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
10 years while eliminating the reliability concerns,
functional disadvantages, and system design
complexities of battery-backed SRAM (BBSRAM).
Fast write timing and virtually unlimited write
endurance make F-RAM superior to other types of
memory.
In-system operation of the FM28V020 is very similar
to other RAM devices and can be used as a drop-in
replacement for standard SRAM. Read and write
cycles may be triggered by /CE or simply by
changing the address. The F-RAM memory is
nonvolatile due to its unique ferroelectric memory
process. These features make the FM28V020 ideal
for nonvolatile memory applications requiring
frequent or rapid writes in the form of an SRAM.
Device specifications are guaranteed over the
industrial temperature range -40°C to +85°C.
