ADSP-21479BCPZ-1A

Digital Signal Processor Dsp Overview

The ADSP-21479BCPZ-1A is a high-performance 32-bit/40-bit floating-point digital signal processor from the SHARC family, optimized for audio processing. It features a single-instruction, multiple-data (SIMD) computational architecture with two processing elements (PEX and PEY). The device operates at up to 300 MHz and includes 5 Mbits of on-chip RAM. Key peripherals include an S/PDIF transceiver, four asynchronous sample rate converters, eight serial ports, and a digital applications interface. It supports IEEE 32-bit and 40-bit floating-point formats.

Digital Signal Processor Dsp Feature Summary

• On-Chip Memory: 5 Mbits of SRAM configured across four blocks for code and data storage.
• Audio Peripherals: Includes S/PDIF transceiver, four ASRCs, and precision clock generators.
• Variable Instruction Set: Supports 16-bit, 32-bit, and 48-bit instructions for code density.

Digital Signal Processor Dsp Applications

• High-performance audio processing
• Medical imaging systems
• Communications equipment
• Test and measurement instruments

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with development tools such as the ADSP-2147x EZ-KIT Lite if hardware integration is planned. Check for any recent product change notices regarding assembly or material composition.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high floating-point throughput and extensive on-chip memory. The 88-lead LFCSP_VQ package is suitable for space-constrained designs but lacks the external port found in the BGA variant. Consider the 300 MHz operating frequency when designing clock circuits and power supplies.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2147x family, which also includes the ADSP-21477 and ADSP-21478. It shares source code compatibility with previous SHARC generations like the ADSP-2136x and ADSP-2126x in SISD mode. The ADSP-21479 offers the highest memory capacity within this specific series.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package are limited due to specific memory configurations. The ADSP-21478 may be considered if less on-chip RAM is acceptable, though it has only 3 Mbits. Software migration may be required when moving between different memory capacities within the family.
