AD21489WBSWZ402RL

Overview

The AD21489WBSWZ402RL is a SHARC digital signal processor featuring a 450 MHz operating frequency and 5 Mbits of on-chip RAM. It utilizes a single-instruction, multiple-data (SIMD) architecture with 32-bit/40-bit floating-point capabilities. The device includes an asynchronous memory interface (AMI), eight serial ports, S/PDIF transceivers, and four asynchronous sample rate converters. It operates within a temperature range of -40°C to +125°C and supports AEC-Q100 automotive qualification standards.

Feature Summary

• 450 MHz SIMD core with 32/40-bit floating-point processing
• 5 Mbits on-chip SRAM and 4 Mbits on-chip ROM
• Integrated Digital Applications Interface (DAI) with flexible signal routing
• AEC-Q100 qualified for automotive applications

Applications

• Automotive audio processing systems
• High-performance industrial control
• Surround sound decoding algorithms

Procurement Notes

Verify the specific suffix RL against the manufacturer's current ordering guide to confirm tape-and-reel packaging status. Confirm that the 450 MHz speed grade matches system timing requirements. Ensure compatibility with existing SHARC development tools and codebases.

Selection Notes

Select this model for applications requiring high computational throughput in constrained environments. The 176-lead LQFP package provides extensive peripheral connectivity. Verify external memory interface needs, as the AMI supports up to 6M words in Bank 0.

Part Context

This component belongs to the fourth-generation SHARC family, which includes the ADSP-21483, ADSP-21486, ADSP-21487, and ADSP-21488. All members share source code compatibility and similar architectural features, differing primarily in memory size, clock speed, and package options.

Replacement Considerations

The ADSP-21489WBSWZ402 is a compatible alternative if reel packaging is not required. Other family members like the ADSP-21487 offer lower clock speeds but maintain pin and code compatibility.
