ADAU1463WBCPZ300

Overview

The ADAU1463WBCPZ300 is an automotive-qualified SigmaDSP digital audio processor featuring a 32-bit core operating at up to 294.912 MHz. It provides 48 kWords of data memory and 16 kWords of program memory. The device supports 48-channel, 32-bit digital I/O with sample rates up to 192 kHz via four serial input and four output ports. Key electrical parameters include a digital supply voltage (DVDD) range of 1.14 V to 1.26 V and an analog supply voltage (AVDD) range of 2.97 V to 3.63 V. It integrates eight stereo asynchronous sample rate converters (ASRCs), S/PDIF interfaces, and an 8-channel, 10-bit SAR auxiliary ADC within an 88-lead LFCSP package.

Feature Summary

• Automotive qualified with AEC-Q100 certification for -40°C to +105°C operation
• High-performance 32-bit DSP core running at frequencies up to 294.912 MHz
• Integrated 8-channel, 10-bit SAR auxiliary control ADC and die temperature sensor
• Supports standalone operation with self-boot capability from serial EEPROM

Applications

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

Procurement Notes

Verify the specific suffix '300' indicates the 294.912 MHz core frequency variant with 16 kWords program memory. Confirm that the LFCSP-88 package requires appropriate thermal management due to the exposed pad design. Ensure power supply rails meet the specified tolerances for AVDD, DVDD, PVDD, and IOVDD during system validation.

Selection Notes

Select this component over the ADAU1467 if the application requires 48 kWords of data memory rather than 80 kWords. Choose the ADAU1463WBCPZ150 if a lower core frequency of 147.456 MHz is sufficient for the algorithm complexity. Verify that the host system can support the required SPI or I2C control interface speeds for configuration.

Part Context

This part belongs to the ADAU1463/ADAU1467 family of SigmaDSP processors. It is pin and register compatible with earlier devices like the ADAU1450/1451/1452. The '300' suffix denotes the high-frequency variant compared to the '150' suffix version. It serves as a central audio hub for complex multirate systems requiring extensive channel counts and low latency.

Replacement Considerations

The ADAU1467WBCPZ300 is a direct pin-compatible upgrade offering increased memory (80 kWords data, 24 kWords program). For lower performance needs, the ADAU1463WBCPZ150 offers the same package but runs at half the core frequency.
