Product Summary

The DS1248Y-100 is a fully static nonvolatile RAM (organized as 128k words by 8 bits) with a built-in real-time clock. The DS1248Y-100 has a self-contained lithium energy source and control circuitry, which constantly monitors VCC for an out-of-tolerance condition. When such a condition occurs, the lithium energy source is automatically switched on and writes protection is unconditionally enabled to prevent garbled data in both the memory and real-time clock.
