Product Summary

The DS1213C is a 28-pin, 600 mil DIP socket with a built-in CMOS controller circuit and an embedded lithium energy source. It accepts a 32K x 8 JEDEC byte wide CMOS static RAM. When the DS1213C is mated with a CMOS RAM, it provides a complete solution o problems associated with memory volatility. The DS1213C uses only Pins 20 and 28 for RAM control. All other pins are passed straight through. When such a condition occurs, the internal lithium energy source is automatically switched on and writes protection is unconditionally enabled to prevent data corruption.
