Introduction

The xCORE Array Microphone provides a scalable and flexible hardware and software solution for high-performance, low-cost multi-channel USB microphone aggregators and array microphones. Built around the xCORE-200 series multi-core microcontroller, it directly connects seven PDM (Pulse Density Modulation) microphones and one high-speed USB 2.0 device. Each captured PDM input is converted to a PCM audio stream and transmitted to a host PC or processor via the USB Audio Class protocol. The system can be configured to generate PCM output at sample rates from 7.35kHz to 48kHz, enabling easy interfacing with a range of hosts including application processors or standalone DSPs. The microphone interface library is highly configurable, allowing designers to customize system functionality to meet their specific needs. It is provided in source code form with application notes demonstrating examples of how to modify the code. With the xTIMEcomposer development tools, getting started with the xCORE-200 is straightforward — these tools provide a feature-rich software development environment for rapid and easy customization of customer-specific product differentiation features.
