ADSP-21584KBCZ-4A

Digital Signal Processor Dsp Overview

The ADSP-21584KBCZ-4A is a dual-core SHARC+ digital signal processor from Analog Devices, operating at a maximum clock frequency of 500 MHz per core. It features up to 640 kB of Level 1 SRAM memory per core with optional cache configuration and parity protection. The device includes an integrated Arm Cortex-A5 core running at 500 MHz (800 DMIPS) with 32 kB L1 instruction and data caches, plus 256 kB of shared Level 2 cache. It utilizes a 19 mm × 19 mm 349-ball BGA package and supports 32-bit, 40-bit, and 64-bit floating-point formats alongside 32-bit fixed-point processing.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to confirm package type and temperature range. Ensure compatibility with development tools such as CrossCore Embedded Studio. Check for automotive qualification status if deploying in AEC-Q100 environments.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high floating-point throughput combined with RISC-style programmability. The 349-ball BGA package offers a compact footprint suitable for space-constrained designs. Consider the ADSP-SC584 variant if an Arm Cortex-A5 core is required for system management tasks.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-SC58x/ADSP-2158x family of SHARC processors. It shares architectural similarities with the ADSP-21583 but operates at a higher core frequency. The family is designed for real-time signal processing with low power consumption across automotive temperature ranges.
