Description
Pin Configuration
The FM16W08 is a 64-kilobit nonvolatile memory
employing an advanced ferroelectric process. A
ferroelectric random access memory or F-RAM is
nonvolatile but operates in other respects as a RAM.
It provides data retention for 38 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 F-RAM superior to
other types of nonvolatile memory.

In-system operation of the FM16W08 is very similar
to other RAM devices. Minimum read- and write-
cycle times are equal. The F-RAM memory, however,
is nonvolatile due to its unique ferroelectric memory
process. Unlike BBSRAM, the FM16W08 is a truly
monolithic nonvolatile memory. It provides the same
functional benefits of a fast write without the
disadvantages associated with modules and batteries
or hybrid memory solutions.

Ordering Information
These capabilities make the FM16W08 ideal for
nonvolatile memory applications requiring frequent
or rapid writes in a bytewide environment. The
availability of a true surface-mount package improves
the manufacturability of new designs. Device
specifications are guaranteed over an industrial
temperature range of -40°C to +85°C.
