ADSP-SC598KBPZ8

Digital Signal Processor Dsp Overview

The ADSP-SC598KBPZ8 is a SHARC+ dual-core digital signal processor with an integrated Arm Cortex-A55 core, manufactured by Analog Devices. It operates in a 400-ball BGA_ED package (17 mm × 17 mm, 0.8 mm pitch). The device features two SHARC+ cores running up to 1000 MHz and one Arm Cortex-A55 core running up to 1200 MHz. Memory resources include 2 MB of shared L2 SRAM with ECC protection, 256 kB of L2 cache with ECC, and 5 Mb (640 kB) of L1 SRAM per SHARC+ core. It supports 32-bit, 40-bit, and 64-bit floating-point operations alongside 32-bit fixed-point processing.

Digital Signal Processor Dsp Feature Summary

• Dual-enhanced SHARC+ cores with up to 1000 MHz clock speed and 5 Mb L1 SRAM each
• Arm Cortex-A55 core operating at up to 1200 MHz with NEON/FPU support
• 2 MB on-chip L2 SRAM with ECC and 256 kB L2 cache with ECC
• Integrated cryptographic hardware accelerators and Arm TrustZone security

Digital Signal Processor Dsp Applications

• Automotive audio amplifiers and head units
• Active noise cancellation (ANC) and rear seat entertainment systems
• Digital cockpit and advanced driver assistance systems (ADAS)
• Professional audio mixing consoles and microphone arrays

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., KBPZ8) against the manufacturer's ordering guide to confirm the exact maximum clock frequencies for both the SHARC+ and Cortex-A55 cores. Ensure compatibility with automotive AEC-Q100 requirements if deploying in vehicle environments. Confirm that the 400-ball BGA_ED package dimensions align with the target PCB layout constraints.

Digital Signal Processor Dsp Selection Notes

Select this model over the ADSP-SC596 when dual SHARC+ cores are required for parallel signal processing tasks. The ADSP-SC598 provides two SHARC+ cores compared to the single core in the SC596 variant. Consider the 2 MB L2 SRAM capacity for applications requiring significant on-chip data storage without external memory interfaces. Verify peripheral availability, such as CAN FD and MLB, which may be restricted to automotive-grade versions.

Digital Signal Processor Dsp Part Context

The ADSP-SC598 belongs to the ADSP-SC59x family of processors, designed for high-performance audio and control applications. It shares architectural similarities with the ADSP-2159x series but integrates the Arm Cortex-A55 core for system management. This family targets markets requiring low latency, high floating-point throughput, and robust security features within a compact form factor.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-SC596 serves as a lower-specification alternative with only one SHARC+ core. For pin-compatible upgrades from older generations, the ADSP-2159x series offers similar SHARC+ architecture but lacks the integrated Arm Cortex-A55 core. Verify software compatibility and peripheral mapping differences when migrating between these variants.
