DP8429D-MSP

Controllers Overview

The DP8429D-MSP is a memory controller manufactured by National Semiconductor, housed in a 48-pin DIP package. It utilizes MOS technology and operates within a commercial temperature range up to 70 °C. The component features a maximum slew rate of 325 mA and is constructed with a ceramic body. It is not RoHS compliant and lacks surface mount capabilities.

Controllers Feature Summary

• Integrated memory control functionality for embedded systems
• Robust ceramic packaging suitable for through-hole mounting
• Commercial grade operational temperature rating

Controllers Applications

• Embedded processor memory interfacing
• Industrial control system data storage management
• Legacy computer hardware memory expansion

Controllers Procurement Notes

Verify the specific suffix MSP against official National Semiconductor documentation to confirm exact pinout or voltage variations. Ensure compatibility with existing 5V embedded controller architectures. Confirm that the ceramic DIP-48 form factor fits the target PCB layout constraints. Check for end-of-life status given the manufacturer's history.

Controllers Selection Notes

Select this component when a dedicated MOS-based memory controller in a through-hole ceramic package is required. It suits designs needing commercial temperature stability without extreme environmental ruggedness. Consider the 48-pin footprint and legacy interface requirements before choosing over modern surface-mount alternatives.

Controllers Part Context

National Semiconductor was acquired by Texas Instruments. This part belongs to the legacy embedded processor and controller category. The DP8429 series typically serves as a static RAM controller for microprocessor systems, providing address decoding and timing generation for memory subsystems.

Controllers Replacement Considerations

Check for direct cross-reference numbers from Texas Instruments or third-party distributors. Verify pin-to-pin compatibility if substituting with other DIP-48 memory controllers. Ensure functional equivalence in terms of MOS technology and control logic.
