ADSP-21363BBC-1AA

Digital Signal Processor Dsp Overview

The ADSP-21363BBC-1AA 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 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 six full-duplex serial ports, two SPI-compatible interfaces, an 8-channel asynchronous sample rate converter (ASRC), and precision clock generators. Unlike the ADSP-21362 and ADSP-21365, this model does not include S/PDIF or DTCP modules.

Digital Signal Processor Dsp Feature Summary

• SIMD Core Architecture: Two parallel processing elements (PEX and PEY) supporting IEEE 32-bit and 40-bit floating-point operations.
• On-Chip Memory: 3 Mbits of internal SRAM and 4 Mbits of internal ROM for code and data storage.
• Audio Peripherals: Includes eight channels of asynchronous sample rate converters (ASRC) and six synchronous serial ports.
• Security Features: Supports ROM-based security with JTAG access restricted by a unique 64-bit key.

Digital Signal Processor Dsp Applications

• High-performance automotive audio processing
• Digital signal processing requiring SIMD execution
• Systems utilizing asynchronous sample rate conversion

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with existing development tools and boot configuration settings before integration.

Digital Signal Processor Dsp Selection Notes

Select this model over the ADSP-21362 or ADSP-21365 if S/PDIF and DTCP functionalities are not required. Confirm that the 333 MHz core speed and 3 Mbit SRAM capacity meet the system's performance and memory requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2136x family of SHARC processors. It shares source code compatibility with the ADSP-2126x, ADSP-2116x, and first-generation ADSP-2106x families in SISD mode. The family is designed to eliminate I/O bottlenecks through multiple internal buses.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include the ADSP-21362, ADSP-21364, ADSP-21365, and ADSP-21366. Note that these alternatives may offer different peripheral sets, such as S/PDIF or DTCP support, which must be evaluated for functional equivalence.
