ADSP-21479KBCZ-1A

Digital Signal Processor Dsp Overview

The ADSP-21479KBCZ-1A is a high-performance 32-bit/40-bit floating-point digital signal processor (DSP) from Analog Devices, belonging to the SHARC family. It features a Super Harvard architecture with up to 5 Mbits of on-chip RAM and supports operating frequencies up to 300 MHz. The device includes SIMD computational units, an I/O processor with extensive audio-centric peripherals like S/PDIF transceivers and asynchronous sample rate converters, and interfaces including SPI, UART, and SPORT. It is designed for premium audio processing applications.

Digital Signal Processor Dsp Feature Summary

• High-performance 32-bit/40-bit floating-point DSP with SIMD architecture delivering up to 1.8 GFLOPS at 300 MHz.
• On-chip memory configuration of up to 5 Mbits SRAM and 4 Mbits factory-programmed ROM.
• Integrated audio peripherals including S/PDIF transceiver, four asynchronous sample rate converters, and eight serial ports.
• Code compatible with other SHARC family members and supports Variable Instruction Set Architecture (VISA).

Digital Signal Processor Dsp Applications

• High-performance audio processing
• Premium audio applications requiring advanced decoding
• Automotive audio systems (qualified models)

Digital Signal Processor Dsp Procurement Notes

Verify the specific package type and temperature grade when ordering, as the ADSP-2147x family offers multiple options. Confirm that the selected variant meets the required automotive qualification standards if applicable. Ensure development tools such as CrossCore Embedded Studio are available for programming.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-21479 model for maximum on-chip memory (5 Mbits RAM). Choose the KBCZ suffix for the 88-lead LFCSP_VQ package. Consider the 196-ball BGA package if external memory interfaces or MediaLB are required, as these are not available in the LQFP or LFCSP packages.

Digital Signal Processor Dsp Part Context

This component is part of the ADSP-2147x series, which also includes the ADSP-21477 and ADSP-21478. The ADSP-21479 represents the highest performance tier within this specific generation, offering the largest memory capacity and full peripheral set compared to its siblings.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and pinout include other ADSP-21479 variants with different speed grades or packaging options. For code compatibility, earlier SHARC processors like the ADSP-2146x can be used in SISD mode.
