.. Rev 0; 8/06 3.3V Single-Piece 16Mb Nonvolatile SRAM General Description 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 ponents are encased in a surface-mount module with a 256-ball BGA footprint. Whenever VCC is applied to the module, it recharges the ML battery, powers the SRAM from the external power source, and allows the contents of the SRAM to be modified. When VCC is powered down or out-of-tolerance, the controller write-protects the SRAM’s contents and powers the SRAM from the battery. The DS2070W also contains a power-supply...
