ADSP-21364BBCZ-1AA

Digital Signal Processor Dsp Overview

The ADSP-21364BBCZ-1AA is a 32-bit/40-bit floating-point digital signal processor from the SHARC family, optimized for high-performance audio processing. It features a Single-Instruction, Multiple-Data (SIMD) computational architecture with two processing elements capable of 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 an S/PDIF transceiver, eight-channel asynchronous sample rate converters (SRC), sixteen PWM outputs, and a Digital Audio Interface (DAI) with a flexible Signal Routing Unit (SRU).

Digital Signal Processor Dsp Feature Summary

• SIMD Core Architecture: Two parallel processing elements (PEX/PEY) each containing an ALU, multiplier, and shifter, supporting IEEE 32-bit and 40-bit floating-point formats.
• On-Chip Memory: 3 Mbits of configurable SRAM and 4 Mbits of ROM; supports single-cycle independent accesses by core and I/O processors.
• Audio Peripherals: Integrated S/PDIF receiver/transmitter, 8-channel SRC with up to -140 dB SNR, and 16 PWM outputs configured as four groups of four.
• Digital Audio Interface (DAI): Includes six serial ports, Precision Clock Generators (PCG), Input Data Port (IDP), and a software-configurable Signal Routing Unit (SRU).

Digital Signal Processor Dsp Applications

• High-performance automotive audio processing systems
• Multi-channel digital audio mixing and routing
• Motor and engine control via PWM generation
• Secure audio content playback with DTCP support

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix BBCZ-1AA against the manufacturer's current Ordering Guide to confirm package type (136-ball CSP_BGA or 144-lead LQFP_EP) and temperature range. Ensure that any required security keys for JTAG access are obtained directly from Analog Devices sales offices if ROM-based security features are utilized.

Digital Signal Processor Dsp Selection Notes

Select this model when SIMD performance is required alongside dedicated audio interfaces like S/PDIF and SRC. Note that the ADSP-21364 includes S/PDIF but lacks the DTCP cipher found in the ADSP-21362 and ADSP-21365 models. Verify memory configuration needs against the 3M bit SRAM limit and ensure compatibility with existing SHARC assembly codebases.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2136x family, which shares source code compatibility with the ADSP-2126x, ADSP-2116x, and first-generation ADSP-2106x processors. The ADSP-21364 sits within the lineup offering specific audio decoders in ROM compared to other variants, providing a balance of computational power and specialized audio hardware without the full DTCP suite.

Digital Signal Processor Dsp Replacement Considerations

Direct functional substitutes within the same family include the ADSP-21362, ADSP-21363, ADSP-21365, and ADSP-21366. Differences lie primarily in available ROM-based audio decoders, presence of S/PDIF, and inclusion of the DTCP security protocol. Cross-family migration to ADSP-2126x requires SISD mode adaptation.
