3.3V Single-Piece 4Mb Nonvolatile SRAM  
with Clock  
General Description  
Features  
The DS3050W consists of a static RAM, a nonvolatile  
(NV) controller, a year 2000-compliant real-time clock  
(RTC), and an internal rechargeable manganese lithium  
(ML) battery. These components are encased in a sur-  
face-mount module with a 256-ball BGA footprint.  
Single-Piece, Reflowable, 27mm x 27mm BGA  
Package Footprint  
Internal Manganese Lithium Battery and Charger  
Integrated Real-Time Clock  
Whenever V  
is applied to the module, it recharges  
CC  
the ML battery, powers the clock and SRAM from the  
external power source, and allows the contents of the  
Unconditionally Write-Protects the Clock and  
clock registers or SRAM to be modified. When V

CC  
powered down or out-of-tolerance, the controller write-  
protects the memory contents and powers the clock  
and SRAM from the battery. The DS3050W also con-  
tains a power-supply monitor output (RST), as well as a  
user-programmable interrupt output (IRQ/FT).
