ADAU1463WBCPZ150

Overview

The ADAU1463WBCPZ150 is an automotive-qualified SigmaDSP digital audio processor featuring a 32-bit core operating at a maximum frequency of 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 interfaces, with standalone operation enabled by self-boot from serial EEPROM.

Feature Summary

• Automotive-grade SigmaDSP core running at 147.456 MHz with 48 kWords data and 16 kWords program memory
• 48-channel digital audio I/O supporting TDM, I2S, left/right justified, and PCM formats up to 192 kHz
• Eight stereo ASRCs providing 139 dB dynamic range and flexible sample rate conversion ratios
• Integrated clock oscillator, PLL, on-chip regulator, and temperature sensor for standalone system design

Applications

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

Procurement Notes

Verify the specific suffix WBCPZ150 confirms the 147.456 MHz core frequency variant, distinct from the standard 294.912 MHz ADAU1463WBCPZ. Confirm RoHS compliance and AEC-Q100 qualification status through official Analog Devices documentation prior to integration.

Selection Notes

Select this model over the ADAU1467 when reduced program memory (16 kWords vs. 24 kWords) and lower core frequency are sufficient for the application. Ensure power supply requirements for AVDD, DVDD, PVDD, and IOVDD align with the specified voltage ranges in the electrical characteristics table.

Part Context

This component belongs to the ADAU1463/ADAU1467 family, which shares pin and register compatibility with earlier ADAU1450/1451/1452 devices. The primary distinction between variants lies in memory capacity and DSP core clock speed, with the WBCPZ150 offering optimized performance for cost-sensitive or lower-complexity audio routing tasks.

Replacement Considerations

The ADAU1463WBCPZ serves as a direct functional replacement for the ADAU1452 series in many designs due to pin and register compatibility. Verify that the target application does not require the higher instruction throughput or larger memory pools provided by the ADAU1467 or the 294.912 MHz variant of the ADAU1463.
