AD21479WYCPZ1A02

Overview

The AD21479WYCPZ1A02 is a high-performance 32-bit/40-bit floating-point digital signal processor from Analog Devices, belonging to the SHARC family. It operates at up to 300 MHz and features a Single-Instruction, Multiple-Data (SIMD) computational architecture. The device includes 5 Mbits of on-chip RAM and 4 Mbits of on-chip ROM. It is optimized for audio processing with peripherals such as the Digital Applications Interface (DAI), serial ports, S/PDIF transceiver, and asynchronous sample rate converters. The component is AEC-Q100 qualified for automotive applications.

Feature Summary

• 300 MHz operating frequency with SIMD computational engine
• 5 Mbits on-chip RAM and 4 Mbits on-chip ROM
• AEC-Q100 qualified for automotive applications
• Integrated DAI, SPORTs, S/PDIF, and ASRC peripherals

Applications

• High performance audio processing
• Automotive audio systems
• Medical imaging
• Communications equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type, temperature range, and memory configuration. Ensure compatibility with existing design constraints regarding voltage levels and pinout assignments before procurement.

Selection Notes

Select this model when 5 Mbits of internal memory and 300 MHz processing speed are required. The 100-lead LQFP package is suitable for designs needing integrated peripherals without external memory interfaces. Consider the ADSP-21478 if less internal memory is sufficient for the application.

Part Context

This part is a member of the ADSP-2147x family, which also includes the ADSP-21477 and ADSP-21478. These processors share code compatibility with other SHARC family members like the ADSP-2136x and ADSP-2146x series in SISD mode.

Replacement Considerations

The ADSP-21478 offers similar architecture but with 3 Mbits of RAM. The ADSP-21477 provides 2 Mbits of RAM. Verify package and peripheral requirements when substituting.
