ADSP-21573BBCZ-4

Digital Signal Processor Dsp Overview

The ADSP-21573BBCZ-4 is a dual-core SHARC+ digital signal processor integrated with an Arm Cortex-A5 core, manufactured by Analog Devices. It operates at a maximum clock frequency of 500 MHz and utilizes a 400-ball CSP_BGA package. The architecture includes two SHARC+ cores, each equipped with 384 kB of L1 SRAM, and a shared 1 MB L2 SRAM with ECC protection. Key peripherals include a 16-bit DDR controller supporting DDR3/DDR2/LPDDR1, USB 2.0 High-Speed, Gigabit Ethernet (EMAC), SDIO/eMMC, and multiple communication interfaces such as CAN 2.0, SPI, UART, and I2C.

Digital Signal Processor Dsp Feature Summary

• Dual-enhanced SHARC+ cores with up to 500 MHz performance and 384 kB L1 SRAM per core
• Integrated Arm Cortex-A5 core operating at 500 MHz with NEON/VFPv4-D16 support
• 1 MB shared L2 SRAM with Error Correction Code (ECC) protection
• Comprehensive peripheral set including Gigabit Ethernet, USB 2.0 HS, SDIO/eMMC, and CAN 2.0

Digital Signal Processor Dsp Applications

• Automotive infotainment and advanced driver assistance systems (ADAS)
• Professional audio processing and mixing consoles
• Industrial motor control and automation systems

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'BBCZ-4' against the manufacturer's current ordering guide to confirm package type, temperature range, and lead-free compliance status. Ensure compatibility with automotive qualification standards if deploying in AEC-Q100 environments. Cross-reference pin assignments for the 400-ball CSP_BGA package during schematic design.

Digital Signal Processor Dsp Selection Notes

Select this model when high-performance floating-point DSP capabilities are required alongside a general-purpose application processor. The ADSP-21573 variant specifically provides both SHARC+ cores active, unlike single-core counterparts. Consider the 1 MB L2 memory capacity for complex algorithm storage and the extensive peripheral interface options for system integration without external controllers.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-SC57x/ADSP-2157x family, which combines SHARC+ SIMD DSP cores with Arm Cortex-A5 processors. The ADSP-21573 is the dual-core SHARC+ variant within this series, distinguished from the SC573 by the absence of the Arm Cortex-A5 core in some configurations, though the datasheet indicates the SC57x/2157x naming convention covers these hybrid architectures. It serves as a successor to earlier SHARC-only devices like the ADSP-21569.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and feature set include the ADSP-SC573BBCZ-4. For applications requiring only one SHARC+ core, the ADSP-SC572BBCZ-4 or ADSP-21571CBCZ-4 may be suitable. Verify software compatibility and pinout equivalence before substituting.
