ADSP-21583KBCZ-4A

Digital Signal Processor Dsp Overview

The ADSP-21583KBCZ-4A is a dual-enhanced SHARC+ digital signal processor featuring two cores operating at a maximum frequency of 450 MHz. It delivers up to 2.7 GFLOPS per core with support for 32-bit, 40-bit, and 64-bit floating-point formats alongside 32-bit fixed-point processing. Each core includes up to 640 kB of configurable L1 SRAM with parity protection. The device integrates a shared 256 kB L2 SRAM with ECC, a 512 kB L2 ROM, and a 16-bit memory controller supporting DDR3, DDR2, or LPDDR1 SDRAM. It operates within an automotive temperature range and utilizes a 349-ball BGA package.

Digital Signal Processor Dsp Feature Summary

• Dual SHARC+ cores running at 450 MHz providing high-performance floating-point DSP capabilities
• Integrated 256 kB L2 SRAM with Error Correction Code (ECC) protection for data integrity
• Hardware accelerators including FFT/IFFT, FIR/IIR filters, and cryptographic engines
• Automotive-grade qualification (AEC-Q100) with low power consumption across the operating temperature range

Digital Signal Processor Dsp Applications

• Multi-axis motor control systems
• Energy distribution management
• Professional audio processing
• Automotive infotainment and sensor fusion

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix KBCZ-4A against the manufacturer's current datasheet to confirm package type, temperature grade, and revision status. Ensure compatibility with CrossCore Embedded Studio development tools for software deployment. Confirm that the 349-ball BGA footprint matches the target PCB design constraints.

Digital Signal Processor Dsp Selection Notes

Select this model when dual-core SHARC+ performance at 450 MHz is required without the Arm Cortex-A5 application processor found in SC58x variants. It is suitable for applications needing dedicated DSP acceleration with hardware security features but lacking real-time OS requirements handled by an ARM core. Verify L1/L2 memory configuration needs against the 640 kB per core and 256 kB shared limits.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2158x family, which shares architecture with the ADSP-SC58x series but excludes the integrated Arm Cortex-A5 core. It is designed for applications requiring high-efficiency signal processing with lower system complexity compared to the mixed-signal SC58x counterparts. The part is RoHS compliant and available in a 19 mm x 19 mm package.

Digital Signal Processor Dsp Replacement Considerations

Direct functional substitutes include other members of the ADSP-2158x family such as the ADSP-21584 or ADSP-21587, provided clock speed and peripheral availability match the design requirements. For legacy upgrades, consider backward compatibility with previous SHARC generations like the ADSP-214xx series.
