3.3V 4096K Nonvolatile SRAM with Battery Monitor

Part Number	Status
DS1350W	Active: In Production. See Ordering Information for details.

The DS1350W 3.3V 4096k Nonvolatile SRAM is a 4,194,304-bit, fully static, nonvolatile SRAM organized as 524,288 words by eight 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. Additionally, the DS1350W has dedicated circuitry for monitoring the status of V_CC and the status of the internal lithium battery. DS1350W devices in the PowerCap Module package are directly surface mountable and are normally paired with a DS9034PC PowerCap to form a complete Nonvolatile SRAM module. The devices can be used in place of 512k x 8 SRAM, EEPROM or Flash components.
