ADSP-21363KBCZ-1AA

Digital Signal Processor Dsp Overview

The ADSP-21363KBCZ-1AA is a high-performance 32-bit/40-bit floating-point SHARC processor optimized for automotive audio applications. It features a SIMD computational architecture with two processing elements delivering up to 2 GFLOPS at a core clock 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 interfaces, an input data port (IDP), precision clock generators, and pulse-width modulation outputs. Unlike other family members, the ADSP-21363 lacks S/PDIF and SRC capabilities.

Digital Signal Processor Dsp Feature Summary

• SIMD SHARC Core: Two processing elements (PEX/PEY) supporting IEEE 32-bit and 40-bit floating-point and 32-bit fixed-point operations.
• On-Chip Memory: 3 Mbits of configurable SRAM and 4 Mbits of ROM for code/data storage.
• Digital Audio Interface (DAI): Includes six serial ports, IDP, PCG, PWM, and flexible signal routing via SRU.
• Security Features: ROM-based security with JTAG access restricted by a unique 64-bit key.

Digital Signal Processor Dsp Applications

• Automotive audio processing systems
• High-performance digital signal processing requiring SIMD architecture
• Applications utilizing parallel port or SPI interfaces for peripheral control

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix KBCZ-1AA against the manufacturer's current ordering guide to confirm package type (CSP_BGA vs LQFP_EP) and temperature grade. Ensure compatibility with CrossCore Embedded Studio development tools. Check for RoHS compliance status in the latest datasheet revision.

Digital Signal Processor Dsp Selection Notes

Select the ADSP-21363 when S/PDIF and Asynchronous Sample Rate Converter (SRC) functionalities are not required, as these are exclusive to other models in the ADSP-2136x family. This model provides identical core performance and memory resources but omits the dedicated audio decoder ROM found in the ADSP-21365. Verify pinout compatibility if migrating from ADSP-21362 or ADSP-21364.

Digital Signal Processor Dsp Part Context

The ADSP-21363 belongs to the ADSP-2136x family of SHARC processors, which are source-code compatible with previous generations like the ADSP-2126x and ADSP-2116x. It shares the same Super Harvard Architecture and SIMD engine as siblings such as the ADSP-21362 and ADSP-21365, differing primarily in integrated peripheral availability and ROM content.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the ADSP-2136x family include the ADSP-21362, ADSP-21364, ADSP-21365, and ADSP-21366. Note that substituting with models containing S/PDIF or SRC may require software adjustments if those unused peripherals are referenced in the original design.

Digital Signal Processor Dsp FAQ

Does the ADSP-21363 support S/PDIF transmission?

No, the ADSP-21363 does not include an S/PDIF receiver/transmitter. This feature is available only on the ADSP-21362, ADSP-21364, and ADSP-21365 models.

What is the maximum core clock frequency for this processor?

The ADSP-21363 supports a maximum core instruction rate of 333 MHz, enabling peak performance of 2 GFLOPS in SIMD mode.

How is the internal memory configured?

The device contains 3 Mbits of on-chip SRAM and 4 Mbits of mask-programmable ROM. The SRAM can be configured for various word sizes (16-bit, 32-bit, 48-bit, or 64-bit) to optimize code or data storage.
