DS1213C

Overview

The DS1213C is a SmartSocket SRAM memory controller IC manufactured by Analog Devices Inc./Maxim Integrated. It integrates nonvolatile memory management functions into a single component, designed for systems requiring reliable data retention without external battery monitoring circuitry. The device operates within a supply voltage range of 4.75V to 5.5V and supports through-hole mounting in a 28-PDIP package with a standard pin spacing of 0.600 inches (15.24mm). It is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Integrates SmartSocket SRAM control logic for automated nonvolatile memory management
• Eliminates the need for external battery backup switching circuits
• Supports parallel interface communication for system bus integration

Applications

• Industrial control systems requiring persistent configuration storage
• Embedded hardware initialization and testing environments
• Data logging applications needing automatic write-back protection

Procurement Notes

Verify current manufacturing status as the DS1213C is listed as obsolete and no longer in production. Confirm availability of qualified replacement components from authorized distributors before finalizing design specifications. Ensure compatibility with existing PCB footprints if substituting with equivalent-density NV SRAM modules or alternative SmartSocket controllers.

Selection Notes

Select this component only when legacy support for Maxim SmartSocket architecture is required. Compare against modern NVSRAM alternatives that offer similar density and interface compatibility. Evaluate thermal performance within the specified 0°C to 70°C range for the intended application environment. Verify power supply stability within the 4.75V to 5.5V operational window to ensure proper controller function.

Part Context

The DS1213C belongs to the DS1213 series of SmartSocket SRAM controllers. These devices were designed to simplify the implementation of nonvolatile memory in microprocessor-based systems by handling battery backup detection and switching internally. The series typically pairs with specific SRAM densities to provide complete nonvolatile storage solutions.

Replacement Considerations

The M48Z35-70PC1 from STMicroelectronics is documented as a similar substitute part number for this obsolete component.
