ADSP-21364YSWZ-2AA

Digital Signal Processor Dsp Overview

The ADSP-21364YSWZ-2AA is a high-performance 32-bit/40-bit floating-point SHARC processor optimized for automotive audio applications. Operating at up to 333 MHz, it delivers 2 GFLOPS using a Single-Instruction, Multiple-Data (SIMD) architecture with two processing elements. The device integrates 3 Mbits of on-chip SRAM and 4 Mbits of mask-programmable ROM. Key peripherals include an S/PDIF transceiver, eight-channel asynchronous sample rate converters, and a Digital Audio Interface with a flexible signal routing unit. It supports IEEE single-precision and extended-precision floating-point formats alongside 32-bit fixed-point operations.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix YSWZ-2AA against the manufacturer's current ordering guide to confirm package type, temperature range, and boot configuration options. Ensure compatibility with development tools such as the ADZS-21369-EZLITE kit if hardware validation is required. Check for RoHS compliance status in the latest datasheet revision.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring source code compatibility with previous SHARC generations while needing dedicated audio peripherals like S/PDIF and SRC. Compare memory configurations with the ADSP-21362 or ADSP-21365 if DTCP security features are not needed. Consider the 144-lead LQFP_EP package constraints for PCB layout and thermal management.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2136x family, which shares architectural features with the ADSP-2126x and ADSP-2116x SIMD SHARC processors. It maintains assembly-level code compatibility with first-generation ADSP-2106x processors in SISD mode. The family is designed to eliminate I/O bottlenecks through multiple internal buses and specialized audiocentric peripherals.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21362, ADSP-21363, ADSP-21365, and ADSP-21366 are pin-compatible members of the same family. Selection depends on specific peripheral requirements, such as the presence of S/PDIF, SRC, or DTCP modules, rather than core performance differences.
