ADSP-21573CBCZ-5

Digital Signal Processor Dsp Overview

The ADSP-21573CBCZ-5 is a dual-core SHARC+ digital signal processor with an integrated Arm Cortex-A5 core, operating at a maximum frequency of 500 MHz. It features two SHARC+ cores, each equipped with up to 3 MB (384 kB per block) of L1 SRAM configurable as cache or memory. The device includes 1 MB of shared L2 SRAM with ECC protection and supports DDR3/DDR2/LPDDR1 via a 16-bit interface. Key peripherals include Gigabit Ethernet (EMAC), USB 2.0 High Speed, SDIO/eMMC, and multiple audio interfaces such as DAI, SPORT, and S/PDIF. It is housed in a 17 mm × 17 mm 400-ball CSP_BGA package.

Digital Signal Processor Dsp Feature Summary

• Dual-enhanced SHARC+ SIMD cores with up to 500 MHz operation and 32/40/64-bit floating-point support
• Integrated Arm Cortex-A5 core with NEON/VFPv4-D16, 32 kB L1 I/D cache, and 256 kB L2 cache
• 1 MB shared L2 SRAM with ECC and 16-bit controller for DDR3/DDR2/LPDDR1 external memory
• Comprehensive peripheral set including Gigabit Ethernet, USB 2.0 HS, SDIO/eMMC, and 2× CAN 2.0

Digital Signal Processor Dsp Applications

• Automotive infotainment and advanced driver assistance systems (ADAS)
• Professional audio processing and networked audio platforms
• Industrial control and motor drive applications requiring high-performance DSP

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature range and 'BZ' denotes lead-free RoHS compliance with BGA packaging. Confirm the '-5' suffix corresponds to the 500 MHz speed grade against the manufacturer's current ordering guide. Ensure compatibility with automotive AEC-Q100 requirements if applicable, noting that standard variants may differ from qualified automotive grades.

Digital Signal Processor Dsp Selection Notes

Select this model when both high-throughput floating-point DSP capabilities and RISC-based system management are required in a single package. The ADSP-21573 provides more GPIOs and peripherals than the ADSP-SC572 or ADSP-21571. Consider the ADSP-SC573 only if the Arm Cortex-A5 core is necessary for OS execution; otherwise, the ADSP-21573 offers similar DSP performance without the ARM core overhead.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-SC57x/ADSP-2157x family, which unifies SHARC+ DSP and Arm Cortex-A5 technologies. The ADSP-21573 variant specifically excludes the Arm Cortex-A5 core found in the SC573, focusing purely on dual SHARC+ performance while retaining the same peripheral richness and package options. It serves as a high-end solution within the SHARC portfolio for complex signal processing tasks.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-SC573 is a functional equivalent that adds an Arm Cortex-A5 core. For pure DSP replacement without ARM needs, the ADSP-21573 is the direct counterpart. Check the ordering guide for updated suffixes regarding temperature ranges and package types, as revisions may alter availability or minor electrical characteristics.
