DESCRIPTION

The DS1350 4096k Nonvolatile SRAMs are 4,194,304-bit, fully static, nonvolatile SRAMs organized as

524,288 words by 8 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 DS1350 devices have dedicated circuitry for monitoring the

status of V_CCand the status of the internal lithium battery. DS1350 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.
