AD21488WBCPZ302

Overview

The AD21488WBCPZ302 is a fourth-generation SHARC digital signal processor from Analog Devices, designed for high-performance audio processing. It features a single-instruction, multiple-data (SIMD) computational architecture supporting 32-bit fixed-point and 32/40-bit floating-point arithmetic. The device operates at a maximum clock frequency of 400 MHz and includes 5 Mbits of on-chip RAM and 4 Mbits of on-chip ROM. It is housed in an 88-lead LFCSP package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• High-performance SIMD core with 32-bit/40-bit floating-point capabilities optimized for audio algorithms.
• Integrated memory structure comprising 5 Mbits of SRAM and 4 Mbits of mask-programmable ROM.
• AEC-Q100 qualification ensuring reliability for automotive environments.
• Variable Instruction Set Architecture (VISA) support for code density optimization.

Applications

• Automotive audio systems requiring robust DSP performance.
• High-fidelity audio processing and surround sound decoding.
• Industrial control applications utilizing hardware filter accelerators.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and temperature range. Ensure compatibility with development tools such as CrossCore Embedded Studio. Confirm supply status directly with authorized distributors as availability may vary by region.

Selection Notes

Select this model when automotive qualification (AEC-Q100) is required alongside 400 MHz processing speed. Compare internal RAM configurations against other family members like the ADSP-21489 if higher clock speeds are needed. Verify that the 88-lead LFCSP package meets board space constraints compared to larger LQFP options.

Part Context

This component belongs to the ADSP-2148x family of fourth-generation SHARC processors. It shares architectural similarities with the ADSP-21483, ADSP-21486, ADSP-21487, and ADSP-21489, offering source code compatibility with previous SHARC generations including the ADSP-2126x and ADSP-2136x series.

Replacement Considerations

The ADSP-21489 offers similar features but operates at up to 450 MHz. The ADSP-21483 provides identical specifications but lacks certain automotive qualifications depending on the variant. All devices in the ADSP-2148x family are pin-compatible within their respective package types.
