DS1350W Description

Each NV SRAM 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 write protection is unconditionally enabled to prevent data corruption. Additionally, the DS1350W has dedicated circuitry for monitoring the status of VCC and the status of the internal...
