ADSP-21587KBCZ-5B

Digital Signal Processor Dsp Overview

The ADSP-21587KBCZ-5B is a dual-core SHARC+ digital signal processor integrated with an Arm Cortex-A5 core, operating at a maximum clock frequency of 500 MHz. It features up to 640 kB of Level 1 SRAM per SHARC+ core and 256 kB of shared Level 2 SRAM with ECC protection. The device includes a 512 kB Level 2 ROM and supports external memory interfaces for DDR3, DDR2, and LPDDR1 SDRAM. Packaged in a 529-ball BGA, it provides extensive connectivity including USB 2.0 HS, Ethernet MACs, PCIe, and multiple digital audio interfaces.

Digital Signal Processor Dsp Feature Summary

• Up to 5 Mb L1 SRAM per SHARC+ core and 256 kB shared L2 SRAM with ECC
• Comprehensive peripheral set including USB 2.0 HS, PCIe 2.0, and dual EMAC

Digital Signal Processor Dsp Applications

• Automotive infotainment and control systems
• Professional audio processing and mixing consoles
• Industrial motor control and high-performance floating-point applications

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix '5B' against the manufacturer's current ordering guide to confirm package type and temperature range specifications. Ensure compatibility with the required PCB footprint for the 529-ball BGA package. Confirm RoHS compliance status for the specific manufacturing lot prior to integration into production designs.

Digital Signal Processor Dsp Selection Notes

Select this component when both real-time DSP processing and complex system control are required within a single package. The ADSP-21587 offers higher performance than the ADSP-SC582/SC583 variants due to its dual SHARC+ cores. Consider the 529-ball BGA package constraints and thermal requirements for automotive or industrial environments when finalizing the design.

Digital Signal Processor Dsp Part Context

This processor belongs to the ADSP-SC58x/ADSP-2158x family, which shares architectural similarities with the ADSP-2159x series but targets different performance and pin-count requirements. It is code-compatible with previous generation SHARC processors at the assembly level, facilitating migration from legacy designs while providing enhanced cache and branch prediction features.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-SC587KBCZ-5B serves as the direct equivalent within the SC58x product line. For pin-compatible upgrades requiring higher clock speeds, the ADSP-21593KBCZ series may be considered, though software adaptation is required.
