Built around the xCORE-200 series of multicore microcontrollers, it provides direct interfacing to seven PDM (Pulse Density Modulation) microphones and a high speed USB2.0 device. Each captured PDM input is converted into a PCM audio stream and transferred to the host PC or processor via USB Audio Class protocol. The system can be configured to generate PCM output at sample rates from 7.35kHz to 48kHz, making it simple to interface to a range of hosts including Applications Processors or standalone Digital Signal Processors. The microphone interface library is highly configurable and enables designers to customize the functionality of the system to meet their specific requirements. It is supplied as source code and accompanied by application notes which show examples of how to modify the code. Getting started with xCORE-200 couldn’t be easier thanks to the xTIMEcomposer™ development tools which provide a feature-rich software development environment with quick and easy customization for customer specific, product differentiating features. xCORE Array Microphone PRODUCT BRIEF FUNCTIONAL BLOCK DIAGRAM: xCORE Array Microphone APPLICATIONS     Microphone aggregation Multi-channel USB microphones Array microphones Personal home robots and VDAs     Smart TVs and soundbars Smart home security devices Camera direction control Conferencing EVALUATION BOARD Features  XUF216 multicore microcontroller  7 PDM MEMS microphones  3.5mm headphone jack  Connectivity options o USB device (micro-B) o 10/100Mbps Ethernet  User interface: 4 buttons, 13 LEDs  xTAG interface for JTAG debug 90mm DEVELOPMENT TOOLS The xTIMEcomposer™ tool suite provides everything you need to write, debug and test applications for xCORE-200 multicore microcontrollers.
