Description

General part information

DS1345W Series

The DS1345W 3.3V 1024k NV SRAM is a 1,048,576-bit, fully static, nonvolatile SRAM organized as 131,072 words by 8 bits. Each NV SRAM has a self-contained lithium energy source and control circuitry, which constantly monitors VCCfor 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 DS1345W has dedicated circuitry for monitoring the status of VCCand the status of the internal lithium battery. DS1345W 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 128k x 8 SRAM, EEPROM or Flash components.
