Developing multichannel and Hi-Res USB audio solutions

Our flexible multicore microcontrollers are easy to programme, pack big processing power and enable you to implement functions alongside USB that traditionally require dedicated hardware. So if you’re looking for real-time, high-performance processing, flexible silicon that gives you scalable solutions and shorter go-to market timescales then take a look at our xCore-200 range. It’s ideal for hi-res consumer audio and complex multichannel professional audio applications.

Asynchronous clock

Ideal for bit perfect transfer of audio data, including I2C, TDM, S/PDIF, DSD and ADAT

Multiple channels

Ideal for multichannel audio applications that need high-performance, scalable channel counts from 1 to 32.

Low latency

Ideal for Hi-Res audio products that stream low jitter, bit perfect audio: PCM 384kHz, DSD512, DoP.

xCORE-200 multicore microcontrollers are available in a range of resource densities, packages, performance and temperature grades to fit your needs. And our engineers are on hand to help you move rapidly from prototype to tuning, and from testing to volume production with world-class audio products.

Silicon

The general-purpose L-series (XL/XLF) lets you decide the exact range of interfaces, algorithms and control software your application requires. It offers a peak compute performance of 4000MIPS and up to 1024KB on-chip SRAM memory. Plus there’s an embedded flash option for applications where additional security is required.

The XU/XUF series (USB-enabled) with integrated USB 2.0 PHYs are ideal for all USB Audio applications. Package sizes include the 48pin QFP packages (ideal for headphones and USB DACs), 16 core devices in TQFP and FGBA packages and top of the range 32-core devices with two USB PHYs. Combined with our USB Audio 2.0 software solutions (which enable MFi developers to design Apple devices that operate in USB Host Mode and in USB Device Mode with support for USB Role Switch) these devices deliver the speed and efficiency, robust bit perfect audio streaming and flexible-format audio connectivity required by today’s audio applications.
