ADSP-21375BSWZ-2B

Digital Signal Processor Dsp Overview

The ADSP-21375BSWZ-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 delivering up to 1.596 GFLOPS at a 266 MHz core instruction rate. The device integrates 0.5 Mbits of on-chip SRAM and 2 Mbits of mask-programmable ROM. Key peripherals include four serial ports, a digital applications interface (DAI), a digital peripheral interface (DPI), two SPI ports, one UART, and one TWI interface. It is housed in a 208-lead LQFP_EP package.

Digital Signal Processor Dsp Feature Summary

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 the required development environment, such as VisualDSP++, for software deployment. Check for any RoHS compliance documentation relevant to the manufacturing date code.

Digital Signal Processor Dsp Selection Notes

Select this component over the ADSP-21371 if the application requires 0.5 Mbits of SRAM and 2 Mbits of ROM rather than larger memory capacities. Note that the ADSP-21375 lacks the S/PDIF transceiver and Pulse-Width Modulation (PWM) outputs found in the ADSP-21371 variant. Confirm that four serial ports are sufficient for the system's I/O requirements.

Digital Signal Processor Dsp Part Context

This processor belongs to the SHARC family, which is source-code compatible with ADSP-2126x, ADSP-2136x, and ADSP-2116x DSPs. It utilizes Analog Devices' Super Harvard Architecture, featuring separate program and data buses to eliminate I/O bottlenecks. The device supports context switching and zero-overhead hardware circular buffer support via dual Data Address Generators (DAGs).

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21371 is a pin-compatible alternative within the same datasheet offering larger memory (1M bit SRAM, 4M bit ROM) and additional peripherals like S/PDIF and PWM. Other SHARC family members may require software adaptation despite architectural similarities.
