ADSP-21366BSWZ-1AA

Digital Signal Processor Dsp Overview

The ADSP-21366BSWZ-1AA is a high-performance 32-bit/40-bit floating-point digital signal processor from the SHARC family, optimized for automotive audio applications. Operating at a core instruction rate of up to 333 MHz, it delivers two GFLOPS using its single-instruction, multiple-data (SIMD) computational architecture. The device integrates 3M bits of on-chip SRAM and 4M bits of mask-programmable ROM. It features dedicated audiocentric peripherals including an S/PDIF transceiver, eight-channel asynchronous sample rate converters, pulse-width modulation outputs, and a digital applications interface with a flexible signal routing unit.

Digital Signal Processor Dsp Feature Summary

• SHARC SIMD Core: Two processing elements (PEX/PEY) delivering 2 GFLOPS at 333 MHz with IEEE 32-bit and 40-bit floating-point support.
• On-Chip Memory: 3M bits of internal SRAM and 4M bits of internal ROM for code and data storage.
• Audio Peripherals: Includes S/PDIF receiver/transmitter, 8-channel SRC, DTCP cipher, and 16 PWM outputs.
• Digital Audio Interface: Features six serial ports, precision clock generators, and a configurable signal routing unit.

Digital Signal Processor Dsp Applications

• High-performance automotive audio processing
• Multichannel audio decoding and post-processing
• Motor and engine control via PWM generation

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'BSWZ' against the manufacturer's ordering guide to confirm package type (LQFP_EP) and temperature range. Ensure the '1AA' revision matches the required firmware or silicon version. Confirm RoHS compliance status as per the latest datasheet revision J documentation.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring source code compatibility with existing SHARC processors while needing enhanced audio-specific peripherals. The ADSP-21366 includes audio decoders in ROM and supports DTCP, distinguishing it from lower-tier models like the ADSP-21363. Verify that the 144-lead LQFP_EP package fits the board layout constraints.

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. It is designed to be code-compatible at the assembly level with previous generations. The ADSP-21366 specifically offers higher integration of audio security protocols compared to other members of the series.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21365 is a compatible alternative within the same family, offering similar performance but with different peripheral configurations regarding DTCP and audio decoder ROM content. Cross-referencing the specific memory map and peripheral availability is required before substitution.
