ADSP-21366KBCZ-1AA

Digital Signal Processor Dsp Overview

The ADSP-21366KBCZ-1AA is a high-performance 32-bit/40-bit floating-point digital signal processor from the SHARC family, optimized for automotive audio applications. It features a single-instruction, multiple-data (SIMD) computational architecture 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). It is housed in a 136-ball CSP_BGA package.

Digital Signal Processor Dsp Feature Summary

• SHARC SIMD Core: Dual processing elements (PEX/PEY) with IEEE 754 floating-point support and single-cycle fetch of one instruction and four operands.
• On-Chip Memory: 3 Mbits SRAM and 4 Mbits ROM; includes ROM-based security with 64-bit JTAG key authentication.
• Audio Peripherals: Integrated S/PDIF receiver/transmitter, 8-channel SRC with up to -140 dB SNR, and DTCP cipher support.
• Digital Audio Interface (DAI): Features six serial ports, two SPI interfaces, Precision Clock Generators (PCG), and a flexible Signal Routing Unit (SRU).

Digital Signal Processor Dsp Applications

• High-performance automotive audio processing systems
• Multichannel digital audio decoding and post-processing
• Motor and engine control via Pulse-Width Modulation (PWM)
• Medical imaging and communications equipment

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix KBCZ-1AA against the manufacturer's current Ordering Guide to confirm package type (136-ball CSP_BGA) and temperature range. Ensure compliance with RoHS directives as indicated in the datasheet specifications. Confirm that the required boot configuration pins match the target system design.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high throughput audio processing with integrated copy protection (DTCP) and sample rate conversion. Compare against ADSP-21362 or ADSP-21365 if DTCP is not needed but other features are similar. Ensure the system design supports the 333 MHz core clock and provides adequate power delivery for the internal voltage domains.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2136x family, which shares source code compatibility with the ADSP-2126x and ADSP-2116x series. The ADSP-21366 specifically distinguishes itself by including both S/PDIF and SRC capabilities, unlike the ADSP-21363 which lacks these audio-specific blocks.

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-21364, or ADSP-21365, provided their specific peripheral configurations (e.g., presence of DTCP or SRC) meet the application requirements.
