Nonvolatile SRAM  
General Description  
Features  
Single-Piece, Reflowable, (27mm)2 PBGA Package  
The DS2070W is a 16Mb reflowable nonvolatile (NV)  
SRAM, which consists of a static RAM (SRAM), an NV  
controller, and an internal rechargeable manganese  
lithium (ML) battery. These components are encased in  
a surface-mount module with a 256-ball BGA footprint.

the controller write-protects the SRAM’s contents and  
powers the SRAM from the battery. The DS2070W also  
contains a power-supply monitor output, RST, which can  
be used as a CPU supervisor for a microprocessor.
