How to replace a DS1213 SmartSocket with an equivalent-density NV SRAM module

The DS1213 SmartSocket products have reached end of life and can be replaced using a pin-compatible, equivalent-density 5V NV SRAM module product. With that replacement module product, the customer will be installing a complete, one-piece memory solution guaranteed to provide at least 10 years of data retention life. The replacement product easily doubles the operational lifetime of the equivalent SmartSocket-based configuration.

With the diminishing production of PDIP SRAMs of any density, the decision to identify a replacement product may be accelerated by procurement problems to locate compatible memory chips. The DS12xx-family of NV SRAM modules includes a very low-power SRAM component, which eliminates the two-component procurement requirement of the past. The "AB" version of those modules allows for a ±5 percent operational power-supply tolerance, which matches the electrical characteristics of the previous DS1213-equipped installation.
