DESCRIPTION  
The DS1345 1024k NV SRAMs are 1,048,576-bit, fully static, NV SRAMs organized as 131,072 words  
by 8 bits. Each NV SRAM has a self-contained lithium energy source and control circuitry which  
constantly monitors VCC 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 DS1345 devices have dedicated circuitry for monitoring the status of  
VCC and the status of the internal lithium battery. DS1345 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 128k x 8 SRAM, EEPROM, or Flash components.
