ADSP-21363YSQZ-2AA

Digital Signal Processor Dsp Overview

The ADSP-21363YSQZ-2AA is a high-performance 32-bit/40-bit floating-point SHARC processor optimized for automotive audio applications. It features a single-instruction, multiple-data (SIMD) computational architecture with two processing elements delivering up to 2 GFLOPS at a core instruction rate of 333 MHz. The device integrates 3 Mbits of on-chip SRAM and 4 Mbits of mask-programmable ROM. Key peripherals include six full-duplex serial ports, two SPI interfaces, an 8-channel asynchronous sample rate converter (ASRC), precision clock generators (PCG), and a flexible signal routing unit (SRU). It lacks S/PDIF and DTCP modules found in other family members.

Digital Signal Processor Dsp Feature Summary

• SIMD Architecture: Two parallel processing elements (PEX, PEY) enable efficient execution of math-intensive algorithms like FFTs and filters.
• On-Chip Memory: Includes 3 Mbits of configurable SRAM and 4 Mbits of ROM for code storage and security.
• Audio Peripherals: Features an 8-channel ASRC, Precision Clock Generators (PCG), and a Digital Audio Interface (DAI) with Signal Routing Unit (SRU).
• Connectivity: Provides six synchronous serial ports, two SPI-compatible interfaces, and a 20-bit parallel input data port (PDAP).

Digital Signal Processor Dsp Applications

• High-performance automotive audio processing systems
• Digital signal processing requiring low-latency sample rate conversion
• Complex filter implementations using SIMD capabilities

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix YSQZ-2AA against the manufacturer's current ordering guide to confirm package type (LQFP_EP or BGA) and temperature range. Ensure compatibility with existing board layouts if replacing earlier revisions. Check for RoHS compliance status as per the latest datasheet revision J.

Digital Signal Processor Dsp Selection Notes

Select this model over ADSP-21362 or ADSP-21365 as it excludes S/PDIF and DTCP modules, reducing complexity if digital transmission protection is not required. The ADSP-21363 shares the same core performance and memory size as the ADSP-21364 but differs in peripheral availability. Confirm that the 333 MHz operating frequency meets system timing requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2136x family of SHARC processors, which are source-code compatible with previous generations like the ADSP-2126x and ADSP-2116x. The family is designed to offer significant performance improvements over first-generation SISD SHARC processors through enhanced parallelism and dedicated audio peripherals.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements within the family include ADSP-21362, ADSP-21364, ADSP-21365, and ADSP-21366. Note that these alternatives may include additional peripherals such as S/PDIF transceivers or DTCP ciphers, which must be accounted for in software configuration.
