XVF3800-QF60B-C

Overview

The XMOS XVF3800-QF60B-C is a voice processing unit (VPU) designed for far-field voice capture using microphone arrays. It supports up to four MEMS microphone inputs and operates with 3.3V I/O. The device integrates advanced signal processing pipelines including beamforming, acoustic echo cancellation, and noise suppression to enhance speech recognition and communication quality in noisy environments. Packaged in a 60-lead QFN, it serves as a dedicated hardware accelerator for smart home devices, conferencing systems, and IoT applications requiring robust voice interaction capabilities.

Feature Summary

• Supports up to 4 microphone inputs for far-field voice capture
• Integrated digital signal processing pipeline for beamforming and echo cancellation
• 3.3V I/O voltage compatibility
• Available in a compact 60-lead QFN package

Applications

• Smart home voice assistants
• Video conferencing systems
• IoT voice-enabled devices

Procurement Notes

Verify the specific ordering suffix -C against the manufacturer's official documentation to confirm any variations in temperature range or packaging specifications. Ensure that the 60QFN footprint matches the target PCB design constraints. Confirm that the supply chain source provides genuine XMOS components to avoid counterfeit risks associated with specialized audio processors.

Selection Notes

Select this model when a solution supporting up to four microphones is required for improved spatial audio processing compared to dual-microphone alternatives. Consider the 60QFN package size relative to available board space. Evaluate power consumption requirements against the device's operational specifications to ensure adequate thermal management within the final product enclosure.

Part Context

The XVF3800 belongs to XMOS's XVF family of voice processors, which are optimized for array-based microphone systems. This series addresses the growing demand for hands-free voice control in consumer electronics by providing dedicated hardware acceleration for complex audio algorithms, reducing the processing load on main host CPUs.

Replacement Considerations

Direct replacements may include other members of the XMOS XVF series, such as the XVF3000 or XVF3610, depending on the required number of microphone channels and specific feature sets. Verify pin-to-pin compatibility and firmware support before substituting.
