ADSP-21573KBCZ-4

Digital Signal Processor Dsp Overview

The ADSP-21573KBCZ-4 is a SHARC+ dual-core digital signal processor from Analog Devices, featuring two high-performance floating-point cores and an Arm Cortex-A5 core. Each SHARC+ core operates at up to 500 MHz with 3 Mb (384 kB) of L1 SRAM per core, supporting 32-bit, 40-bit, and 64-bit floating-point formats. The Arm Cortex-A5 core runs at 500 MHz with 800 DMIPS performance. The device includes 1 MB of on-chip L2 SRAM with ECC protection and an L3 interface for DDR3/DDR2/LPDDR1 SDRAM. It is housed in a 17 mm × 17 mm 400-ball CSP_BGA package.

Digital Signal Processor Dsp Feature Summary

• Dual-enhanced SHARC+ cores operating at up to 500 MHz each
• Arm Cortex-A5 core running at 500 MHz with NEON/VFPv4-D16 support
• Up to 1 MB shared L2 SRAM with ECC protection
• Integrated cryptographic accelerators and Arm TrustZone security

Digital Signal Processor Dsp Applications

• Automotive audio amplifiers and head units
• Active Noise Cancellation (ANC) and Road Noise Cancellation (RNC)
• Digital cockpit and advanced driver assistance systems (ADAS)

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix KBCZ against the manufacturer's current data sheet to confirm package type, temperature range, and automotive qualification status. Ensure compatibility with existing PCB footprints for the 400-ball BGA configuration before procurement.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-density signal processing with integrated system control via the Arm Cortex-A5. Compare L1 SRAM configurations and peripheral availability against other members of the ADSP-2157x family to ensure sufficient memory and I/O resources for the target design.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-SC57x/ADSP-2157x family of SHARC+ dual-core DSPs. It shares architectural similarities with the ADSP-SC59x series but offers different clock speeds and peripheral sets tailored for specific performance and power requirements within the automotive and industrial sectors.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same family include the ADSP-SC573 or ADSP-21573 variants, provided that clock speed and peripheral requirements match. Verify that any substitute part maintains the required automotive qualification and package dimensions.
