ADSP-1080AKD

Overview

The ADSP-1080AKD is an 8-bit digital signal processor featuring a DSP-multiplier architecture. It is housed in a hermetically sealed CDIP40 ceramic package with side brazed construction, designated by the JESD-30 code R-CDIP-T40. The component operates within a maximum temperature of 70 °C and utilizes a lead-based termination system that does not comply with RoHS standards. It features an 8-bit external data bus width and a 16-bit output data bus width. The device measures 50.8 mm in length and contains 40 terminals.

Feature Summary

• Hermetically sealed ceramic construction for environmental protection
• Integrated DSP-multiplier for high-speed arithmetic operations
• Side brazed DIP packaging for secure mechanical mounting

Applications

• Military aerospace systems requiring radiation hardening
• Industrial control environments demanding long-term stability
• Defense communication equipment needing hermetic sealing

Procurement Notes

Verify the specific lot traceability and hermetic seal integrity upon receipt, as this is a specialized military-grade component distributed by Rochester Electronics. Confirm compliance with project-specific material declarations, noting the lead-based composition and non-RoHS status. Ensure storage conditions maintain the hermetic barrier before installation to prevent moisture ingress or degradation of the ceramic-metal seal during soldering processes.

Selection Notes

Select this component when hermetic sealing is mandatory for reliability in harsh environments. The 8-bit architecture suits applications where legacy compatibility or specific multiplier throughput is required. Consider the physical dimensions and through-hole mounting requirements associated with the CDIP40 package. Evaluate thermal management needs against the 70 °C maximum operating limit.

Part Context

This part belongs to the ADSP-1000 series of 8-bit microcontrollers and processors. It is typically sourced from Rochester Electronics, which provides aftermarket support for discontinued or specialized Analog Devices components. The ADSP-1080AKD represents a variant optimized for ruggedized applications compared to standard commercial equivalents.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the specific hermetic CDIP40 configuration. Verify functional equivalence of the DSP-multiplier core if substituting with other ADSP-10xx variants. Ensure any alternative maintains the required hermetic seal rating and voltage levels.
