PART DS2045W-100 TEMP RANGE -40°C to +85°C PIN-PACKAGE 256 Ball 27mm2 BGA Module w 8051 MICROPRO

Rev 1; 1/05 w 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.

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 control
