AD21478WYSWZ2B02

Overview

The AD21478WYSWZ2B02 is a SHARC family digital signal processor featuring a 32-bit/40-bit floating-point SIMD computational architecture. It operates at a clock rate of 266 MHz with a core voltage of 1.20 V and I/O voltage of 3.30 V. The device integrates 3 Mbits of on-chip RAM and 4 Mbits of factory-programmed ROM containing audio decoders. It is housed in a 100-lead LQFP package with an exposed pad (14x14 mm) and supports automotive applications.

Feature Summary

SIMD Core: Dual processing elements (PEX, PEY) delivering up to 1.8 GFLOPS performance.
Memory Configuration: 3 Mbits internal SRAM and 4 Mbits internal ROM for secure code execution.
Audio Peripherals: Includes Digital Applications Interface (DAI), S/PDIF transceiver, and Asynchronous Sample Rate Converters (ASRC).
Automotive Grade: Qualified under AEC-Q100 standards for automotive environments.

Applications

High-performance audio processing systems
Automotive infotainment and control units
Digital signal processing requiring SIMD acceleration

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm the specific suffix '2B02' matches the required factory-programmed ROM content and automotive qualification grade. Check current availability status as supply may be limited.

Selection Notes

Select this model when 266 MHz processing speed and 3 Mbits of RAM are sufficient for the application. Ensure the 100-LQFP package fits the PCB layout constraints. Verify that the 4 Mbits of pre-loaded ROM meets the specific audio decoder requirements without needing external storage.

Part Context

This part belongs to the ADSP-2147x family, which includes the ADSP-21477 and ADSP-21479. It shares architectural compatibility with previous SHARC generations while offering enhanced SIMD capabilities and dedicated audio peripherals optimized for high-fidelity sound processing.

Replacement Considerations

Direct substitutes within the same package include the ADSP-21477 (lower frequency/memory) or ADSP-21479 (higher memory/frequency). Verify pinout and software compatibility before substitution.
