ADAU1467WBCPZ300

Digital Signal Processor Dsp Overview

The ADAU1467WBCPZ300 is an automotive-qualified SigmaDSP digital audio processor featuring a 294.912 MHz, 32-bit core operating at 1.2 V. It provides 24 kWords of program memory and 80 kWords of parameter/data RAM, supporting up to 6144 SIMD instructions per sample at 48 kHz. The device includes four serial input ports, four serial output ports, stereo S/PDIF interfaces, and four PDM microphone channels. It integrates eight stereo asynchronous sample rate converters (ASRCs) with 139 dB dynamic range, an on-chip regulator generating 1.2 V from a 3.3 V supply, and standalone self-boot capability from serial EEPROM.

Digital Signal Processor Dsp Feature Summary

• Automotive qualified with a high-performance 294.912 MHz SigmaDSP core for low-latency audio processing.
• Extensive I/O including 48-channel digital audio support, 8 stereo ASRCs, and dedicated PDM microphone inputs.
• Flexible clock generation with integer PLL and support for non-standard sample rates via hardware routing matrix.
• Standalone operation enabled by self-boot from serial EEPROM and master/slave I2C/SPI control interfaces.

Digital Signal Processor Dsp Applications

• Automotive head units
• Rear seat entertainment systems
• Trunk amplifiers
• Commercial and professional audio processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix WBCPZ300 confirms the 294.912 MHz core frequency and 80 kWords data memory configuration. Ensure compatibility with the 88-lead LFCSP package dimensions during PCB layout. Confirm that the design supports the required AVDD, PVDD, and IOVDD voltage ranges specified in the electrical characteristics table.

Digital Signal Processor Dsp Selection Notes

Select this model over the ADAU1463 variant when higher program memory (24 kWords vs. 16 kWords) and larger data RAM (80 kWords vs. 48 kWords) are required for complex algorithms. The 300 suffix denotes the maximum core frequency; verify if lower frequency variants meet power consumption targets. Ensure the application utilizes the full 88-lead package footprint and thermal pad requirements.

Digital Signal Processor Dsp Part Context

The ADAU1467 is pin and register compatible with the ADAU1463 and earlier ADAU1450/1451/1452 processors. It represents an evolution in the SigmaDSP family with restructured hardware optimized for efficient stream and multirate processing. The device serves as a central audio hub, simplifying complex multi-rate system designs through integrated clock generators and ASRCs.

Digital Signal Processor Dsp Replacement Considerations

The ADAU1463WBCPZ300 is functionally identical but offers reduced memory (16 kWords program, 48 kWords data). The ADAU1463WBCPZ150 operates at half the core frequency (147.456 MHz) with the same memory as the standard ADAU1463.
