ADSP-21266SKSTZ-2D

Digital Signal Processor Dsp Overview

The ADSP-21266SKSTZ-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 surround sound decoders. Key interfaces include six full-duplex serial ports, an SPI port, a parallel port, and a Digital Application Interface (DAI) with a Signal Routing Unit (SRU). Power supplies require 1.2 V for internal/analog domains and 3.3 V for external I/O.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'SKSTZ-2D' against the manufacturer's current Ordering Guide to confirm package type, temperature range, and lead time specifications. Ensure compatibility with development tools such as CrossCore Embedded Studio or VisualDSP++ for software integration.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-density on-chip memory and dedicated hardware audio decoding capabilities. The 200 MHz speed and SIMD architecture are suitable for complex FFT and filter operations. Compare against ADSP-21261 and ADSP-21262 based on required SRAM size (1 Mbit vs 2 Mbit) and presence of ROM-based audio decoders.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2126x family of SHARC embedded processors, which also includes the ADSP-21261 and ADSP-21262. These processors share source code compatibility at the assembly level with previous generations like the ADSP-21160 and ADSP-2106x. The family is optimized for cost-effective, high-performance audio processing solutions.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21261 and ADSP-21262 are pin-compatible members of the same family. Selection depends on memory requirements: ADSP-21261 has 1 Mbit SRAM and no ROM decoders, while ADSP-21262 has 2 Mbit SRAM but lacks the specific ROM decoder algorithms found in the ADSP-21266.
