ADSP-21375KSWZ-2B

Digital Signal Processor Dsp Overview

The ADSP-21375KSWZ-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 1.596 GFLOPS at a 266 MHz core instruction rate. The device integrates 0.5 Mbit of on-chip SRAM and 2 Mbit 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 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 match the target PCB footprint requirements. Confirm RoHS compliance status as indicated in the latest datasheet revision.

Digital Signal Processor Dsp Selection Notes

Select this model over the ADSP-21371 when reduced on-chip memory capacity is sufficient for the application, as the ADSP-21375 lacks the S/PDIF transceiver and PWM outputs found in the ADSP-21371 variant. Verify code compatibility with existing SHARC family software if migrating from previous generation processors like the ADSP-2136x series.

Digital Signal Processor Dsp Part Context

This component belongs to the SIMD SHARC family of digital signal processors. It maintains source code compatibility with the ADSP-2126x, ADSP-2136x, and ADSP-2116x families. The ADSP-21375 serves as a cost-optimized alternative to the ADSP-21371 by providing fewer serial ports and omitting dedicated audio transceivers while retaining the core computational architecture.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21371 is a functionally similar member of the same family but includes an S/PDIF transceiver, eight serial ports, and 1 Mbit of SRAM. Direct substitution requires verifying that the additional resources of the ADSP-21371 do not conflict with board design constraints.
