The MFA hardware is based around the XS1-U6 multicore microcontroller; an XMOS xCORE-USB™ device with an integrated High Speed USB 2.0 PHY and 6 logical cores delivering 500MIPS of deterministic and responsive processing power. Exploiting the flexible programmability of the xCORE™ architecture, the MFA platform supports multiple USB audio streaming formats (PCM, DSD & DoP) at the high sampling rates (PCM up to 384kHz, DSD up to x128) and bit depths (PCM up to 32bits) demanded by the audiophile market. The guaranteed Hardware-Response™ times of xCORE technology always ensure low latency (round trip as low as 3ms), bit perfect audio streaming to and from the USB host. Delivered as source code, the reference software provides a fully featured production ready solution, including support for: Full- and HighSpeed USB operation, USB Audio Class 2.0 & 1.0, MIDI, HID & DFU classes and Apple Host Mode operation. The XMOS xTIMEcomposer™ Studio development suite and tools then allow for quick and easy software development and customisation to add customer specific, product differentiating features.
