ADSP21262SKBCZ200R

Digital Signal Processor Dsp Overview

The ADSP21262SKBCZ200R 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) managed by a Signal Routing Unit (SRU). It supports 22 DMA channels for zero-overhead data transfers.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type, temperature range, and lead time requirements. Ensure compatibility with development tools such as CrossCore Embedded Studio or VisualDSP++ for software integration. Confirm power supply configurations for VDDINT, VDDEXT, and AVDD pins during hardware design.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high throughput in audio decoding or complex mathematical operations. The 200 MHz speed and SIMD architecture offer significant performance gains over previous SISD generations. Consider the ADSP-21261 if lower memory capacity (1 Mbit SRAM, 3 Mbit ROM) and fewer serial ports (4 SPORTs) are sufficient for the application.

Digital Signal Processor Dsp Part Context

The ADSP21262SKBCZ200R belongs to the third-generation SHARC family, succeeding earlier models like the ADSP-21060. It shares assembly-level code compatibility with the ADSP-2116x and ADSP-2136x families. This component represents a shift towards higher integration, combining substantial on-chip memory and programmable I/O to reduce external component counts in system designs.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21261 offers similar architecture but with reduced memory (1 Mbit SRAM, 3 Mbit ROM) and only four serial ports. The ADSP-21266 includes additional ROM-based audio decoders compared to the ADSP-21262. Verify pinout and memory configuration differences when substituting.
