ADSP-21371BSWZ-2B

Digital Signal Processor Dsp Overview

The ADSP-21371BSWZ-2B 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 1.596 GFLOPS at a 266 MHz core instruction rate (3.75 ns cycle time). The device includes 1 Mbit of on-chip SRAM and 4 Mbit of mask-programmable ROM. Key peripherals include an S/PDIF transceiver, eight serial ports, four precision clock generators, and a flexible signal routing unit within the Digital Applications Interface. It operates in a 208-lead LQFP_EP package.

• High-quality audio signal processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'BSWZ-2B' against the manufacturer's current ordering guide to confirm pinout, temperature range, and packaging details. Ensure compatibility with existing design infrastructure regarding the 208-lead LQFP_EP package dimensions and thermal requirements.

Digital Signal Processor Dsp Selection Notes

Select this model for designs requiring high-performance floating-point DSP capabilities with integrated audio interfaces. Compare internal memory sizes against the ADSP-21375 variant if lower cost or reduced peripheral count (no PWM, fewer serial ports) is acceptable. Ensure software development tools support the SIMD SHARC family architecture.

Digital Signal Processor Dsp Part Context

This component belongs to the third-generation SHARC processor family from Analog Devices. It shares source code compatibility with previous SHARC members like the ADSP-2136x and ADSP-2126x series. The ADSP-21371 variant specifically targets high-end audio applications compared to the feature-reduced ADSP-21375.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21375 is a compatible alternative within the same family, offering identical core performance but with reduced memory (0.5 Mbit SRAM, 2 Mbit ROM) and fewer peripherals (no PWM, four serial ports, no S/PDIF). Verify pin-to-pin compatibility and software migration requirements.
