DESCRIPTION
The DS1258W 3.3V 128k x 16 Nonvolatile SRAM is a 2,097,152-bit, fully static, nonvolatile (NV)
SRAM, organized as 131,072 words by 16 bits. Each NV SRAM has a self-contained lithium energy
source and control circuitry, which 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 DS1258W devices can be used in place
of solutions which build nonvolatile 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.
