ADSP-21266SKBCZ-2D

Digital Signal Processor Dsp Overview

The ADSP-21266SKBCZ-2D is a high-performance 32-bit/40-bit floating-point digital signal processor from the SHARC family, operating at a core instruction rate of 200 MHz. It features a Single-Instruction Multiple-Data (SIMD) architecture with two computational units delivering up to 1200 MFLOPS. The device integrates 2 Mbit dual-ported SRAM and 4 Mbit mask-programmable ROM containing multichannel audio decoders. Key interfaces include six serial ports, an SPI port, a parallel port, and a Digital Application Interface (DAI). It operates on 1.2 V for internal/analog supplies and 3.3 V for I/O.

Digital Signal Processor Dsp Feature Summary

• Digital Application Interface (DAI) with Signal Routing Unit (SRU)
• Six full-duplex serial ports and 22-channel DMA controller

Digital Signal Processor Dsp Applications

• High-performance audio decoding and postprocessing
• Multichannel surround sound systems
• Professional audio equipment requiring low system costs

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'SKBCZ-2D' against the manufacturer's official ordering guide to confirm package type, temperature range, and boot configuration options. Ensure compatibility with required development tools such as CrossCore Embedded Studio or VisualDSP++ for software implementation.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high throughput in audio processing algorithms like FFTs and FIR filters. Compare memory configurations against the ADSP-21261 and ADSP-21262 if lower capacity suffices. Ensure the design supports the necessary 1.2 V and 3.3 V power rails and utilizes the DAI for flexible peripheral connectivity.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2126x series, which includes the ADSP-21261 and ADSP-21262. These processors share code compatibility at the assembly level with other SHARC DSPs like the ADSP-21160 and ADSP-21060. The ADSP-21266 specifically offers the highest memory capacity within this subset.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21262SBBCZ-150 is a related part within the same family but operates at 150 MHz and contains 4 Mbit ROM. Verify functional requirements before substitution.
