Description  
The FM21L16 is a 128Kx16 nonvolatile memory that  
reads and writes like  
a standard SRAM. A  
The device is available in a 400 mil 44-pin TSOP-II  
surface mount package. Device specifications are  
guaranteed over industrial temperature range –40°C  
to +85°C.  
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, and system design  
complexities of battery-backed SRAM (BBSRAM).  
Fast write timing and high write endurance make  
FRAM superior to other types of memory.  
Pin Configuration  
In-system operation of the FM21L16 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 FM21L16 ideal for  
nonvolatile memory applications requiring frequent  
or rapid writes in the form of an SRAM.  
The FM21L16 includes a low voltage monitor that  
blocks access to the memory array when VDD drops  
below a critical threshold. The memory is protected  
against an inadvertent access and data corruption  
under this condition. The device also features  
software-controlled write protection. The memory
