DS2045W 3.3V Single-Piece 1Mb  
Nonvolatile SRAM  
General Description  
Features  
Single-Piece, Reflowable, 27mm2 PBGA Package  
The DS2045W is a 1Mb 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 DS2045W also  
contains a power-supply monitor output, RST, which can  
be used as a CPU supervisor for a microprocessor.
