DS1213D

Overview

The DS1213D is a SmartSocket SRAM controller housed in a 32-pin DIP package. It accepts standard 32K x 8 or 128K x 8 JEDEC bytewide CMOS static RAMs. The device operates within a voltage range of 4.75V to 5.5V and supports an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates an embedded lithium energy source to retain data during power failures
• Automatically enables write protection when supply voltage drops out of tolerance
• Provides a self-contained circuitry solution for memory volatility issues

Applications

• Protecting volatile memory in battery-backed systems
• Safeguarding data in industrial control environments
• Ensuring data integrity in communication equipment

Procurement Notes

Verify the specific pinout compatibility with the target SRAM module before integration. Confirm that the 32-pin DIP form factor matches the existing PCB footprint requirements. Ensure the system design accommodates the lithium cell replacement constraints if maintenance is required over the long term.

Selection Notes

Select this component when a compact, socket-based solution is needed to protect SRAM data without adding external discrete components. It is suitable for designs requiring automatic write protection and extended data retention using an internal energy source.

Part Context

This part belongs to the DS1213 SmartSocket series from Maxim Integrated. These devices are designed to simplify the implementation of non-volatile memory solutions by combining a controller and power source directly into the IC socket interface.

Replacement Considerations

The DS1213B is a similar 28-pin variant within the same family. Verify pin count differences and physical dimensions before substituting.
