DESCRIPTION  
The DS1220AB and DS1220AD 16k Nonvolatile SRAMs are 16,384-bit, fully static, nonvolatile SRAMs  
organized as 2048 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 2k x 8 SRAMs  
directly conforming to the popular bytewide 24-pin DIP standard. The devices also match the pinout of  
the 2716 EPROM and the 2816 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.
