ADSP-21565KSWZ10

Digital Signal Processor Dsp Overview

The ADSP-21565KSWZ10 is a single-core SHARC+ digital signal processor operating at up to 1 GHz. It features an enhanced SIMD architecture with support for 32-bit, 40-bit, and 64-bit floating-point operations alongside 32-bit fixed-point processing. The device integrates 5 Mb of Level 1 SRAM with parity protection and up to 8 Mb of Level 2 SRAM with ECC. Key system peripherals include hardware accelerators for FIR/IIR filters running at core speed, a comprehensive Digital Audio Interface (DAI), and security engines. It is housed in a 120-lead LQFP_EP package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and package variant against the ordering guide. Confirm RoHS compliance and automotive qualification status if required for the target application. Check for any recent revision updates to the datasheet that may affect pinout or electrical specifications.

Digital Signal Processor Dsp Selection Notes

Select this model for high-performance floating-point audio processing requiring low latency. Ensure the design accommodates the 120-lead LQFP_EP thermal requirements. Verify that the on-chip memory sizes meet algorithm needs before considering external DDR3 interfaces, which are not available in this package.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2156x family of SHARC+ processors. It shares the core architecture with models like the ADSP-21569 but differs in memory configuration and package options. The K suffix typically denotes a specific temperature range or speed bin within the product line.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and pinout include other ADSP-21565 variants with different speed grades or memory sizes. Cross-family migration to older SHARC models requires significant software adaptation due to architectural differences.
