ADSP-21569KBCZ10

Digital Signal Processor Dsp Overview

The ADSP-21569KBCZ10 is a single-core SHARC+ digital signal processor operating at up to 1 GHz. It features 5 Mb (640 kB) of Level 1 SRAM with parity and up to 8 Mb (1 MB) of Level 2 SRAM with ECC protection. The device supports 32-bit, 40-bit, and 64-bit floating-point operations alongside 32-bit fixed-point processing. It includes a 16-bit DDR3/DDR3L memory controller via the L3 interface and is housed in a 17 mm × 17 mm, 400-ball CSP_BGA package.

Digital Signal Processor Dsp Feature Summary

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and package variant against the ordering guide, as the ADSP-2156x family includes multiple configurations. Confirm RoHS compliance status and check for any active Product Change Notifications or End-of-Life notices prior to finalizing procurement plans.

Digital Signal Processor Dsp Selection Notes

Select this model for high-performance floating-point audio and control applications requiring low latency. Ensure the design accommodates the 17 mm × 17 mm 400-ball CSP_BGA footprint. Verify that the system power supply meets the requirements for the 1 GHz operation mode and automotive temperature range if applicable.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2156x series within the SHARC family. It shares architectural similarities with other models like the ADSP-21567 and ADSP-21566 but offers higher performance grades up to 1 GHz. The KBCZ suffix indicates the specific speed grade and 400-ball BGA package configuration.

Digital Signal Processor Dsp Replacement Considerations

Pin-compatible alternatives within the same package include the ADSP-21567 and ADSP-21566, though they operate at lower maximum frequencies. Cross-family replacements require significant redesign due to architectural differences.
