Datasheet: | PDF (93.2K). Click here to download *) |
The DS1251Y 4096K NV SRAM with Phantom Clock is a fully static nonvolatile RAM (organized as 512K words by 8 bits) with a builtin real time clock. The DS1251Y has a selfcontained lithium energy source and control circuitry which constantly monitors VCC for an outof tolerance condition. When such a condition occurs, the lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent garbled data in both the memory and real time clock. |
