ADSP-21369KBPZ-2A

Digital Signal Processor Dsp Overview

The ADSP-21369KBPZ-2A is a high-performance 32-bit/40-bit floating-point SHARC processor optimized for automotive audio applications. It features a SIMD computational architecture with two processing elements (PEx, PEy) delivering up to 2.4 GFLOPS at a 400 MHz core instruction rate. The device integrates 2 Mbits of on-chip SRAM and 6 Mbits of mask-programmable ROM. Key peripherals include an S/PDIF transceiver, four asynchronous sample rate converters, eight serial ports, and a Digital Applications Interface (DAI). It operates within a temperature range of -40°C to +85°C and utilizes a 256-ball BGA_ED package.

Digital Signal Processor Dsp Feature Summary

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix KBPZ-2A against the manufacturer's current datasheet revision H to confirm pinout compatibility and electrical specifications. Ensure that the 256-ball BGA_ED package requirements are met during PCB design. Confirm RoHS compliance status through official documentation prior to integration.

Digital Signal Processor Dsp Selection Notes

Select this component when a 400 MHz floating-point DSP with significant on-chip memory is required for audio-centric applications. The shared memory interface support in the 256-ball BGA package enables multiprocessor systems. Consider the availability of development tools such as the ADZS-21369-EZLITE kit for prototyping and debugging.

Digital Signal Processor Dsp Part Context

The ADSP-21369 belongs to the SHARC family of Super Harvard Architecture Single-Chip Computers. It maintains source code compatibility with previous generations like the ADSP-2126x and ADSP-2116x in SISD mode. The processor represents an evolution in performance, offering increased throughput over earlier models while retaining architectural familiarity for existing software ecosystems.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21367 and ADSP-21368 models have been deleted from the product line as per Revision H of the datasheet. No direct functional substitutes are listed; alternative selection requires evaluating similar SHARC family members or newer generation processors based on performance and peripheral needs.
