DESCRIPTION

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_CCfor 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_CCand 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.
