ADSP-21364BBC-1AA

Digital Signal Processor Dsp Overview

The ADSP-21364BBC-1AA 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 SIMD computational architecture with two processing elements (PEX and PEY). The device features 3 Mbits of on-chip SRAM and 4 Mbits of mask-programmable ROM. It integrates audiocentric peripherals including an S/PDIF transceiver, eight-channel asynchronous sample rate converter (ASRC), precision clock generators, and a flexible digital audio interface (DAI) with signal routing unit.

Digital Signal Processor Dsp Feature Summary

• SIMD Architecture: Two parallel processing elements (PEX/PEY) enable single-instruction, multiple-data execution for efficient signal processing algorithms.
• On-Chip Memory: Includes 3 Mbits of configurable SRAM and 4 Mbits of ROM for code/data storage and security features.
• Audio Peripherals: Integrated S/PDIF receiver/transmitter, 8-channel ASRC with -128 dB SNR, and DTCP cipher support.
• Digital Audio Interface: Features six serial ports, two SPI interfaces, and a programmable signal routing unit (SRU) for flexible peripheral interconnection.

Digital Signal Processor Dsp Applications

• High-performance automotive audio processing systems
• Professional audio decoding and post-processing
• Motor and engine control via PWM generation
• Medical imaging and communications equipment

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix BBC-1AA against the manufacturer's current data sheet revision J to confirm package type, temperature range, and boot configuration options. Ensure development tools such as CrossCore Embedded Studio are compatible with the SHARC family core architecture for software deployment.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring 333 MHz floating-point performance with dedicated audio hardware acceleration. Compare with ADSP-21362 or ADSP-21365 if DTCP security protocols are required, as these features vary across the 2136x family. Confirm that the 144-lead LQFP_EP or 136-ball BGA package fits the target PCB layout constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2136x family of SHARC processors, which are source-code compatible with earlier ADSP-2126x and ADSP-2116x DSPs. The family shares a common Super Harvard Architecture but varies in integrated audio decoders and security modules like DTCP. The ADSP-21364 specifically includes S/PDIF and SRC capabilities but lacks the built-in audio decoders found in the ADSP-21365.

Digital Signal Processor Dsp Replacement Considerations

Direct functional replacements within the same package and pinout include other members of the ADSP-2136x family such as the ADSP-21362, ADSP-21363, ADSP-21365, and ADSP-21366. Verify peripheral availability, specifically S/PDIF and DTCP support, as these differ between variants.
