AD21478WYBCZ2A02

Overview

The AD21478WYBCZ2A02 is an automotive-grade SHARC digital signal processor from Analog Devices, operating at a maximum frequency of 300 MHz. It features a 32-bit/40-bit floating-point SIMD architecture with 3 Mbits of on-chip RAM and 4 Mbits of factory-programmed ROM. The device utilizes a Super Harvard Architecture to support high-performance audio processing. It is housed in a 100-lead LQFP package with exposed pad (EP) and supports interfaces including DAI, DPI, SPI, SPORT, UART, and TWI.

Feature Summary

High-performance 300 MHz 32-bit/40-bit floating-point SIMD core
Automotive qualified (AEC-Q100) with 3 Mbits RAM and 4 Mbits ROM
Audio-centric peripherals: S/PDIF transceiver, ASRC, PCG, IDP/PDAP
Super Harvard Architecture with dual 64-bit data buses

Applications

Premium audio processing systems
Automotive infotainment and sound processing
Digital signal processing requiring high throughput

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm voltage, temperature range, and packaging details. Confirm availability status as automotive-grade components may have restricted supply channels or longer lead times compared to commercial variants.

Selection Notes

Select this model for applications requiring AEC-Q100 qualification and up to 300 MHz processing speed. Ensure the design accommodates the 100-LQFP-EP package dimensions. Verify that the 3 Mbits internal RAM meets memory requirements, as external memory access via the external port is not available in this package type.

Part Context

This component belongs to the ADSP-2147x family, which includes the ADSP-21477, ADSP-21478, and ADSP-21479. The ADSP-21478 variant specifically provides 3 Mbits of RAM and 4 Mbits of ROM, positioned between the 2 Mbit RAM ADSP-21477 and the 5 Mbit RAM ADSP-21479.

Replacement Considerations

Code-compatible replacements within the SHARC family include the ADSP-21477 and ADSP-21479, subject to memory and pinout constraints. Verify package compatibility when substituting with other members of the ADSP-2147x series.
