DESCRIPTION

The DS1350 4096k NV SRAMs are 4,194,304 bit, fully static, NV 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 NV

SRAM module. The devices can be used in place of 512k x 8 SRAM, EEPROM or Flash components.
