Description
The FM20L08 is a 128K x 8 nonvolatile memory that
reads and writes like a standard SRAM. A
ferroelectric random access memory or FRAM 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,
complexities of battery-backed SRAM (BBSRAM).
Fast write timing and unlimited write endurance make
FRAM superior to other types of memory.
In-system operation of the FM20L08 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 FRAM memory is
nonvolatile due to its unique ferroelectric memory
process. These features make the FM20L08 ideal for
nonvolatile memory applications requiring frequent
or rapid writes in the form of an SRAM.
The FM20L08 includes a voltage monitor function
that monitors the power supply voltage. It asserts an
active-low signal that indicates the memory is write-
protected when V
DD
drops below a critical threshold.
When the /LVL signal is low, the memory is
protected against an inadvertent access and data
corruption.
Superior to Battery-backed SRAM Modules
No battery concerns
Monolithic reliability
True surface mount solution, no rework steps
Superior for moisture, shock, and vibration
Resistant to negative voltage undershoots
Low Power Operation

The FM20L08 also features software-controlled write
protection. The memory array is divided into 8
uniform blocks, each of which can be individually
write protected.
Device specifications are guaranteed over the
temperature range -25°C to +85°C.
