DS1258Y Overview
Each NV SRAM has a self-contained lithium energy source and control circuitry that constantly monitors VCC 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...
