Product Summary

The DS1225Y-150 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 monitors VCC for an out–of–tolerance condition. The DS1225Y-150 can be used in place of existing 8K × 8 SRAMs directly conforming to the popular bytewide 28–pin DIP standard. The DS1225Y-150 also matches the pinout of the 2764 EPROM or the 2864 EEPROM, allowing direct substitution while enhancing performance.

Parametrics

DS1225Y-150 absolute maximum ratings: (1)Voltage on Any Pin Relative to Ground: –0.3V to +7.0V; (2)Operating Temperature: 0℃ to 70℃; –40℃ to +85℃ for IND parts; (3)Storage Temperature: –40℃ to +70℃; –40℃ to +85℃ for IND parts; (4)Soldering Temperature: 260℃ for 10 seconds.

Features
