DESCRIPTION  
The DS1225Y 64K Nonvolatile SRAM is a 65,536–bit,  
fully static, nonvolatile RAM organized as 8192 words  
by 8 bits. Each NV SRAM has a self–contained lithium  
energy source and control circuitry which constantly  
directly conforming to the popular bytewide 28–pin DIP  
standard. The DS1225Y also matches the pinout of the  
2764 EPROM or 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 micro-  
processor interfacing.  
monitors V for an out–of–tolerance condition. When  
CC  
such a condition occurs, the lithium energy source is  
automaticallyswitchedonandwriteprotectionisuncon-  
ditionally enabled to prevent data corruption. The NV  
SRAM can be used in place of existing 8K x 8 SRAMs
