ADSP-21563KSWZ8

Digital Signal Processor Dsp Overview

The ADSP-21563KSWZ8 is a single-core SHARC+ digital signal processor operating at up to 800 MHz. It features 5 Mb of Level 1 SRAM with parity and 512 Kb of Level 2 SRAM with ECC protection. The device supports 32-bit, 40-bit, and 64-bit floating-point arithmetic alongside 32-bit fixed-point processing. It includes hardware accelerators for FIR and IIR filters running at core clock speeds, crypto engines, and an extensive peripheral set including DAI, SPORT, S/PDIF, ASRC, and multiple SPI/UART interfaces. The component is housed in a 120-lead LQFP_EP package.

• Digital cockpit and rear seat entertainment systems

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and memory configuration against the official Analog Devices ordering guide, as suffixes may denote variations in performance or temperature ratings. Confirm RoHS compliance and automotive qualification status if required for the target application environment.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-performance floating-point DSP capabilities within a pin-compatible SHARC+ family ecosystem. Ensure sufficient L2 memory (512 Kb) meets data buffering requirements; consider higher-capacity variants like the ADSP-21565 if larger on-chip storage is needed.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2156x series, which offers code compatibility with previous SHARC generations. It serves as a mid-range option in the family, providing 800 MHz performance and 512 Kb L2 memory, positioned between the lower-speed ADSP-21562 and the higher-memory ADSP-21565.

Digital Signal Processor Dsp Replacement Considerations

Pin-compatible alternatives within the same package include the ADSP-21562 (400 MHz) and ADSP-21565 (800 MHz/1 GHz). Verify software compatibility when migrating between speed grades or memory configurations.
