ADSP-21371KSWZ-2B

Digital Signal Processor Dsp Overview

The ADSP-21371KSWZ-2B is a high-performance 32-bit/40-bit floating-point SHARC processor optimized for automotive audio applications. It features a single-instruction, multiple-data (SIMD) computational architecture with two processing elements capable of delivering 1.596 GFLOPS at a core instruction rate of 266 MHz. The device includes 1 Mbit of on-chip SRAM and 4 Mbit of mask-programmable ROM. Key peripherals include an S/PDIF-compatible digital audio receiver/transmitter, eight dual data line serial ports operating up to 33 Mbps, four precision clock generators, and a flexible signal routing unit. It is housed in a 208-lead LQFP_EP package.

Digital Signal Processor Dsp Feature Summary

• 266 MHz SIMD SHARC core delivering 1.596 GFLOPS peak performance
• 1 Mbit internal SRAM and 4 Mbit mask-programmable ROM
• Integrated S/PDIF transceiver and eight high-speed serial ports
• Flexible Digital Applications Interface (DAI) with Signal Routing Unit

Digital Signal Processor Dsp Applications

• Automotive audio processing and surround sound decoding
• Professional audio equipment and mixing consoles
• Medical imaging systems requiring high throughput
• Communications infrastructure and test equipment

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix KSWZ-2B against the manufacturer's current ordering guide to confirm pinout compatibility and temperature range specifications. Ensure that the 208-lead LQFP_EP package dimensions align with the target PCB footprint design constraints before finalizing procurement.

Digital Signal Processor Dsp Selection Notes

Select this model over the ADSP-21375 variant when the application requires the full complement of eight serial ports, the integrated S/PDIF transceiver, and the larger 1 Mbit SRAM capacity. The inclusion of Pulse-Width Modulation (PWM) outputs further distinguishes it from lower-tier family members lacking these specific audio-centric peripherals.

Digital Signal Processor Dsp Part Context

This component belongs to the third-generation SHARC processor family, which maintains source code compatibility with previous ADSP-2136x and ADSP-2126x series devices. It shares architectural similarities with other SIMD SHARC processors while offering enhanced memory bandwidth and dedicated audio interfaces designed to reduce system-level design complexity.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21375 serves as a functional subset within the same family but lacks the S/PDIF transceiver, PWM outputs, and has reduced memory resources. Direct substitution requires verifying if the missing peripheral features are critical for the specific hardware implementation.
