New XMOS XS1-S processors simplify high-speed USB audio design

XMOS has released the third generation of its XS1 event-driven 32-bit embedded processors, the XS1-S Family. The XS1-S devices deliver up to 700 MIPS of real-time performance per core combined with integrated analog functionality, enabling the highest quality, multi-channel USB audio applications. Combined with XMOS industry-standard USB audio IP, the XS1-S Family of devices delivers the lowest latency digital audio interfaces. The first two products available in the XS1-S Family are the single-core XS1-SU1 and the dual-core XS1-SU2.

The XS1-S Family builds upon the predictable real-time performance of the XS1 architecture, offering increased I/O and processing capabilities together with the convience of integrated analog peripherals.

Features

• 32bit XCore embedded processor(s) delivering upto 700 MIPS each
• Software defined I/O for fully-flexible digital peripherals including I2S, TDM, SPDIF AES/EBU.
• High Speed USB 2.0 Phy
• 12-bit 1MSPS Analog to Digital Converter 
• USB bus power compatible
• Standby and deep sleep modes for energy sensitive applications
• Power On Reset, Watchog timer, brownout detect circuits
• On-chip crystal oscillator
• High Speed USB Audio

The first members of the XS1-S Family include single and dual XCore variants with integrated USB 2.0 High Speed Phy, targeted for demanding USB audio interfaces, DJ products, and USB speakers. Using XMOS flexibility, the devices are also designed for intelligent USB peripherals.

XMOS processors combine flexible interfacing, control, and data processing in a single device. The devices, including all digital peripherals, are programmed in software using a C-language development flow, providing both application and I/O flexibility even after deployment.

Pricing and Availability
The single XCore processor XS1-SU1 with integrated High-Speed USB Phy comes in a 96pin dual row BGA and is priced below $5 in 10ku quantities. Sampling now, the XS1-SU1 will be commercially available from Q2. The dual XCore XS1-SU2 device will be sampling from Q3 2012. Further details are available from an XMOS sales representative.
