DESCRIPTION  
The DS1225AB and DS1225AD are 65,536-bit, fully static, nonvolatile SRAMs organized as 8192 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. The NV SRAMs can be used in place of existing 8k x 8 SRAMs directly conforming to  
the popular bytewide 28-pin DIP standard. The devices also match the pinout of the 2764 EPROM and  
the 2864 EEPROM, allowing direct substitution while enhancing performance. There is no limit on the  
number of write cycles that can be executed and no additional support circuitry is required for  
microprocessor interfacing.
