ADSP-2173BST-80

Digital Signal Processor Dsp Overview

The ADSP-2173BST-80 is a single-chip microcomputer from the ADSP-2100 family, optimized for digital signal processing. It operates at a 50 ns instruction cycle time (20 MIPS) using a 10 MHz crystal at 3.3 V. The device integrates 2K words of on-chip program RAM and 2K words of data memory. Key architectural features include three independent computational units (ALU, MAC, Shifter), two serial ports, an 8/16-bit host interface port, and programmable wait state generation. It supports low-power modes with typical dissipation of 70 mW at 3.3 V.

Digital Signal Processor Dsp Procurement Notes

Verify that the specific suffix 'BST-80' corresponds to the 3.3 V, 50 ns speed grade variant as defined in the official Analog Devices datasheet. Confirm package availability matches the 128-lead TQFP or PQFP options listed. Ensure sourcing channels provide documentation confirming the component is an obsolete part number subject to end-of-life status.

Digital Signal Processor Dsp Selection Notes

Select this model when a 3.3 V supply voltage is required, distinguishing it from the 5.0 V ADSP-2171/2172 variants. Choose based on the need for 20 MIPS performance with a 10 MHz external clock. Consider the integrated 2K word program RAM if external boot memory or additional program storage is not desired. Verify compatibility with existing ADSP-2100 family development tools and software libraries.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-217x family, which combines the ADSP-2100 base architecture with enhanced features like bit manipulation instructions and Bus Grant Hang Logic. The ADSP-2173 specifically targets 3.3 V applications, whereas the ADSP-2171 and ADSP-2172 are designed for 5.0 V operation. The family shares code and function compatibility while offering different power and memory configurations.

Digital Signal Processor Dsp Replacement Considerations

No public confirmed substitute part numbers are available in the provided source material. As the ADSP-217x series is marked obsolete, direct replacements may require architectural migration to newer SHARC or Blackfin processors. Consult Analog Devices for current portfolio alternatives.
