AD21477WYCPZ1A02

Overview

The AD21477WYCPZ1A02 is a high-performance 32-bit/40-bit floating-point SHARC digital signal processor optimized for audio processing. It operates at a maximum clock frequency of 200 MHz and features an SIMD computational architecture with two processing elements. The device includes 2 Mbits of on-chip RAM, lacks internal ROM, and supports VISA. Key peripherals include eight serial ports, an S/PDIF transceiver, four asynchronous sample rate converters, and a thermal diode. It is housed in an 88-lead LFCSP_VQ package and is AEC-Q100 qualified.

Feature Summary

• 200 MHz operating frequency with SIMD architecture delivering up to 1.8 GFLOPS
• 2 Mbits on-chip SRAM configured across four memory blocks
• Audio-centric peripherals including S/PDIF transceiver and four ASRCs
• AEC-Q100 automotive qualification

Applications

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

Procurement Notes

Verify the specific suffix '1A02' against the manufacturer's current ordering guide to confirm package type and temperature grade. Confirm availability status as automotive-grade variants may have restricted supply channels. Ensure design-in documentation matches the 88-lead LFCSP_VQ footprint requirements.

Selection Notes

Select this model over the ADSP-21478 or ADSP-21479 if only 2 Mbits of RAM is required and cost optimization is necessary. Note that the 88-lead package does not support external memory interfaces (SDRAM/AMI); external memory access requires the 196-ball BGA variant. Verify peripheral pin availability against the 88-lead lead assignment table.

Part Context

This component belongs to the ADSP-2147x family, which shares source code compatibility with previous SHARC generations like the ADSP-2136x and ADSP-2146x. The ADSP-21477 represents the entry-level configuration within this family, offering reduced memory capacity compared to the 21478 (3 Mbits) and 21479 (5 Mbits) while maintaining identical core performance and peripheral sets.

Replacement Considerations

Direct functional replacements within the same package include other ADSP-21477 variants with different speed grades or temperature ranges. Cross-family migration to ADSP-2146x processors requires software adaptation due to architectural differences.
