DESCRIPTION
The DS1258 128k x 16 nonvolatile (NV) SRAMs are 2,097,152-bit fully static, NV SRAMs, organized as
131,072 words by 16 bits. Each NV SRAM has a self-contained lithium energy source and control
circuitry that constantly monitors V
CC
for an out-of-tolerance condition. When such a condition occurs,
the lithium energy source is automatically switched on and write protection is unconditionally enabled to
prevent data corruption. DIP-package DS1258 devices can be used in place of solutions that build NV
128k x 16 memory by utilizing a variety of discrete components. There is no limit on the number of write
cycles that can be executed and no additional support circuitry is required for microprocessor interfacing.
