ADSP-21478YSWZ-2B

Digital Signal Processor Dsp Overview

The ADSP-21478YSWZ-2B is a SHARC family digital signal processor manufactured by Analog Devices Inc. It features a 32-bit/40-bit floating-point core operating at a clock rate of 266 MHz. The device integrates 3 Mb of on-chip RAM and 4 Mb of factory-programmed ROM containing audio decoders. It operates with a 1.20 V core voltage and 3.30 V I/O voltage, supporting an ambient temperature range of -40°C to 105°C. The component is housed in a 100-LQFP-EP (14x14) package with exposed pads for thermal management.

Digital Signal Processor Dsp Feature Summary

• SHARC architecture with Single-Instruction, Multiple-Data (SIMD) computational capabilities

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix '2B' against the official Analog Devices datasheet to confirm it denotes the 266 MHz speed grade and automotive qualification. Confirm RoHS compliance status and moisture sensitivity level prior to procurement planning.

Digital Signal Processor Dsp Selection Notes

Select this component when a high-throughput floating-point DSP is required for audio or industrial control. Ensure the design accommodates the 100-LQFP-EP package dimensions and provides adequate thermal dissipation for the exposed pad. Verify power supply requirements for both the 1.20 V core and 3.30 V I/O domains.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-2147x series, which includes the ADSP-21477, ADSP-21478, and ADSP-21479 processors. These devices are optimized for high-performance audio processing and share code compatibility within the SHARC family. The ADSP-21478 variant specifically offers 3 Mb of RAM and 266 MHz operation.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-21478KCPZ-1A is a listed alternative in the same product family, though it utilizes an LFCSP-88 package rather than the LQFP-100 form factor. Cross-reference pinouts and memory configurations before substitution.
