Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix '2A' against the manufacturer's current ordering guide to confirm pinout, temperature range, or packaging variations. Ensure compatibility with the ADZS-21369-EZLITE evaluation kit for development. Confirm RoHS compliance status through official documentation before procurement.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring source code compatibility with existing SHARC family processors while needing higher throughput. The 256-ball BGA_ED package supports shared memory interfaces for multiprocessor systems. Consider the 400 MHz speed and SIMD capabilities for complex DSP algorithms like FIR/IIR filters and FFTs.

Digital Signal Processor Dsp Part Context

The ADSP-21369 belongs to the SIMD SHARC family, offering significant performance improvements over previous SISD SHARC generations. It maintains assembly-level code compatibility with ADSP-2126x, ADSP-2116x, and first-generation ADSP-2106x processors. The BBPZ-2A designation indicates a specific variant within the 21369 series, typically denoting package type and speed grade.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21367 and ADSP-21368 are obsolete models removed from the datasheet. No direct pin-compatible replacements are listed; migration should consider the broader SHARC family or newer ADSP-214xx series if architectural changes are acceptable.
