ADSP-21489KSWZ-5B

Digital Signal Processor Dsp Overview

The ADSP-21489KSWZ-5B is a high-performance 32-bit/40-bit floating-point digital signal processor from Analog Devices, belonging to the fourth-generation SHARC family. It features a single-instruction, multiple-data (SIMD) computational architecture optimized for advanced audio processing. The device operates at a maximum clock frequency of 450 MHz and includes 5 Mbits of on-chip RAM and 4 Mbits of on-chip ROM. Key hardware accelerators include FIR, IIR, and FFT units. It supports Variable Instruction Set Architecture (VISA) for code density improvements and integrates extensive peripherals such as the Digital Applications Interface (DAI), S/PDIF transceiver, and asynchronous sample rate converters.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix '5B' against the official Analog Devices ordering guide to confirm package type, temperature range, and revision level. Ensure compatibility with CrossCore Embedded Studio (CCES) or VisualDSP++ development environments for software deployment. Confirm AEC-Q100 qualification status if the application requires automotive-grade reliability standards.

Digital Signal Processor Dsp Selection Notes

Select this model for designs requiring 450 MHz processing speed and 5 Mbits of internal memory. Compare with ADSP-21486 or ADSP-21488 if lower clock speeds or different memory configurations are sufficient. Ensure the 176-lead LQFP_EP package fits the PCB layout constraints. Verify that the system power supply can provide the required 1.1 V core voltage and manage thermal dissipation at maximum operating frequencies.

Digital Signal Processor Dsp Part Context

This component is part of the ADSP-2148x family, which also includes the ADSP-21483, ADSP-21486, ADSP-21487, and ADSP-21488. All members share source code compatibility with previous SHARC generations and offer pin-compatible options across various packages including 176-lead LQFP, 100-lead LQFP, and 88-lead LFCSP.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include ADSP-21489 variants with different suffixes indicating package or temperature variations. For lower performance needs, consider ADSP-21486 or ADSP-21488. Code migration from ADSP-2147x or ADSP-2146x families is supported due to architectural compatibility.
