DS1225AB - 64k Nonvolatile SRAM

The DS1225AB and DS1225AD are 65,536-bit, fully static, nonvolatile SRAMs organized as 8192 words by 8 bits.

• 10 years minimum data retention in the absence of external power.
• Data is automatically protected during power loss.
• Directly replaces 8k x 8 volatile static RAM or EEPROM.
• Unlimited write cycles.
• Low-power CMOS.
• JEDEC standard 28-pin DIP package.
• Read and write access times of 70 ns.
• Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time.
• Full ±10% VCC operating range (DS1225AD).
• Optiona.
