Functional Overview
The FM28V102A is a 64 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 FM28V102A 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 FM28V102A 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.
