FM22L16  
4-Mbit (256K × 16) F-RAM Memory  
4-Mbit (256K  
× 16) F-RAM Memory  
44-pin thin small outline package (TSOP) Type II  
Features  
Restriction of hazardous substances (RoHS) compliant  
4-Mbit ferroelectric random access memory (F-RAM) logically  
organized as 256K × 16  
Configurable as 512K × 8 using UB and LB  
High-endurance 100 trillion (1014) read/writes  
151-year data retention (see the Data Retention and  
Endurance table)  
NoDelay™ writes  
Page mode operation to 25-ns cycle time  
Advanced high-reliability ferroelectric process  
Functional Description  
The FM22L16 is a 256K × 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.  
SRAM compatible  
Industry-standard 256K × 16 SRAM pinout  
55-ns access time, 110-ns cycle time  
The FM22L16 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 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 FM22L16 ideal for nonvolatile  
memory applications requiring frequent or rapid writes.  
Advanced features  
Software-programmable block write-protect  
Superior to battery-backed SRAM modules  
No battery concerns  
Monolithic reliability  
True surface mount solution, no rework steps  
Superior for moisture, shock, and vibration  
The FM22L16 includes a low voltage monitor that blocks access  
to the memory array when VDD drops below VDD min. The  
memory is protected against an inadvertent access and data  
corruption under this condition. The device also features  
software-controlled write protection. The memory array is  
divided into 8 uniform blocks, each of which can be individually  
write protected.  
Low power consumption  
Active current 8 mA (typ)  
Standby current 90 A (typ)  
Sleep mode current 5 A (max)  
Low-voltage operation: VDD = 2.7 V to 3.6 V  
Industrial temperature: –40 C to +85 C  
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.
