ADAU1463WBCPZ150RL

Overview

The ADAU1463WBCPZ150RL is an automotive-qualified SigmaDSP digital audio processor featuring a 32-bit core operating at 147.456 MHz. It provides up to 48 kWords of data memory and 16 kWords of program memory within an 88-lead LFCSP package. The device supports 48-channel, 32-bit digital I/O at sample rates up to 192 kHz, including four serial input/output ports, stereo S/PDIF interfaces, and four PDM microphone channels. Integrated asynchronous sample rate converters (ASRCs) offer 139 dB dynamic range with ratios from 1:8 to 7.75:1. Control is managed via independent slave and master I²C/SPI ports, enabling standalone operation through self-boot from serial EEPROM.

Feature Summary

• 48 kWords data memory and 16 kWords program memory
• Eight asynchronous sample rate converters (ASRCs) with 139 dB dynamic range
• Four serial input/output ports supporting TDM, I2S, and PCM formats
• Integrated S/PDIF transmitter/receiver and four PDM microphone inputs

Applications

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

Procurement Notes

Verify the specific suffix '150' confirms the 147.456 MHz core frequency variant, distinct from the 294.912 MHz ADAU1463WBCPZ300. Confirm the 'RL' suffix indicates tape and reel packaging for automated assembly. Ensure the design accounts for the 88-lead LFCSP thermal requirements and the exposed pad connection for heat dissipation.

Selection Notes

Select this model over the ADAU1467 when the application requires lower power consumption or reduced instruction throughput, as the ADAU1463 offers less memory and half the clock speed. Verify that the 147.456 MHz core frequency meets the real-time processing demands of the intended audio algorithms. Ensure compatibility with the 88-lead LFCSP footprint if replacing higher-pin-count predecessors like the ADAU1452.

Part Context

This component belongs to the ADAU146x family of SigmaDSP processors, which are pin and register compatible with earlier ADAU145x devices. The ADAU1463 serves as the lower-performance variant compared to the ADAU1467, sharing the same package and interface capabilities but differing in memory size and maximum core frequency. It is designed for complex multirate audio systems requiring flexible clock generation and extensive digital I/O.

Replacement Considerations

The ADAU1463WBCPZ300 is a functional substitute with identical pinout but double the core frequency and memory. The ADAU1467WBCPZ300 offers further increased memory resources. Direct replacement with ADAU1452 series devices requires software adaptation due to architectural differences despite pin compatibility.
