... Optional industrial temperature range of -40°C to +85°C, designated IND DESCRIPTION The DS1225AB and DS1225AD are 65,536-bit, fully static, nonvolatile SRAMs organized as 8192 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control circuitry which constantly monitors V for an out-of-tolerance condition. When such a condition occurs, the lithium ...
