ADSP-1081ATD

Overview

The ADSP-1081ATD is an 8-bit digital signal processor multiplier manufactured by Analog Devices Inc. It is housed in a hermetically sealed ceramic dual in-line package with side brazing, designated as CDIP28 or DIP-28. The device features a 28-pin configuration and operates within an extended temperature range from -55 °C to +125 °C. It supports an external data bus width of 8 bits and provides an output data bus width of 16 bits. The component is classified as a DSP peripheral and is identified by the JESD-30 code R-CDIP-T28.

Feature Summary

• Hermetically sealed ceramic construction for environmental protection
• Side-brazed packaging technology ensuring structural integrity
• Extended industrial operating temperature capability

Applications

• Harsh environment digital signal processing
• Military aerospace systems requiring hermetic sealing
• High-reliability embedded control applications

Procurement Notes

Verify the specific suffix designation to confirm the hermetic seal status and package variant. Ensure compatibility with existing board layouts for the CDIP28 footprint. Confirm that the 8-bit external data bus interface aligns with the system memory architecture. Validate that the operating temperature range meets the environmental requirements of the target application.

Selection Notes

Select this component when hermetic sealing is mandatory for reliability in extreme conditions. The 8-bit external bus requires careful interface design with the host system. Consider the physical dimensions of the DIP-28 package during mechanical integration. Verify power supply requirements against the system voltage rails before implementation.

Part Context

This part belongs to the ADSP-1081 series of digital signal processors. It represents a specialized variant designed for high-reliability applications where standard plastic packages are insufficient. The manufacturer focuses on providing robust solutions for defense and aerospace sectors requiring long-term stability.

Replacement Considerations

Direct substitutes must match the hermetic ceramic DIP-28 package and 8-bit external bus specification. Verify pinout compatibility and electrical parameters before substitution. Generic commercial equivalents may lack the required hermetic sealing.
