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.
The device is available in a 28-pin SOIC, 28-pin
TSOP-I, or 32-pin TSOP-I surface mount package.
Device specifications are guaranteed over the
industrial temperature range -40°C to +85°C.
