ADSP-21565BSWZ10

Digital Signal Processor Dsp Overview

The ADSP-21565BSWZ10 is a single-core SHARC+ digital signal processor from Analog Devices, operating at a maximum clock frequency of 1 GHz. It features an enhanced SIMD architecture supporting 32-bit, 40-bit, and 64-bit floating-point operations alongside 32-bit fixed-point processing. The device integrates 5 Mb (640 kB) of Level 1 SRAM with parity protection and up to 8 Mb (1 MB) of Level 2 SRAM with ECC. It includes hardware accelerators for FIR/IIR filters running at core speed, a crypto engine, and a comprehensive set of peripherals including multiple SPORTs, S/PDIF interfaces, and I2C/SPI controllers. The component is housed in a 120-lead LQFP_EP package and is qualified under AEC-Q100 standards.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and package configuration against the official Analog Devices ordering guide. Confirm that the suffix 'BSWZ10' corresponds to the 1 GHz performance bin and 120-lead LQFP_EP package variant. Ensure compliance with RoHS directives and check for any recent product change notices affecting availability or specifications.

Digital Signal Processor Dsp Selection Notes

Select this model when high-performance floating-point processing is required within automotive temperature ranges. The 1 GHz speed grade is suitable for complex audio algorithms and real-time control loops. Consider the integrated L2 memory size to determine if external DDR3/DDR3L interfaces are necessary for larger data sets.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-2156x family, which shares the SHARC+ core architecture. Variants within the family differ primarily in L2 memory capacity (up to 8 Mb) and maximum clock speeds (ranging from 400 MHz to 1 GHz). The ADSP-21565 specifically offers a balance of high-speed processing and substantial on-chip memory for demanding signal processing tasks.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and pinout include other ADSP-2156x variants such as the ADSP-21569BSWZ10, provided the memory and peripheral requirements match. Lower speed grades like the ADSP-21565BSWZ8 may be used if performance margins allow.
