A second-generation single-chip solution for USB 3.0 flash drives offers enhanced performance using today’s popular flash memories. The VL751 from Via Labs has been certified by the USB Implementers Forum (USB-IF) for SuperSpeed operation, ensuring high-quality, seamless interoperability, and effortless backward compatibility.



The Via Labs VL751 features a four-channel NAND interface, doubling or even quadrupling maximum throughput over single or dual-channel designs. The second generation controller offers improved parallelization and higher efficiency through integrated pre-read and pre-write buffers, better support for popular flash memories, and a pipelined ECC engine. Cumulatively, these enhancements translate into a nearly 100% performance boost over the Via Labs VL750 with no increase in power consumption.

The Via Labs VL751 features USB mass storage class “Bulk-Only Transport” for universal compatibility across platforms such as Windows, Mac OSX and Linux without the need for additional drivers. Featuring a 4-channel memory controller with interleaving support, blistering fast data transfer speeds of 120 Mbyte/s or more are within reach. Via Labs VL751 is fully compliant with the USB 3.0 specification, and is also backwards compatible with USB 2.0 and 1.1 standards, offering class-leading performance in USB 2.0 mode with transfer speeds of up to 35 Mbyte/s.

In addition to high performance, the Via Labs VL751 is also designed for ease of implementation and support. Powered by advanced in-house PHYs, Via Labs VL751 is a single-chip solution that offers outstanding signal integrity characteristics while supporting popular 2X-3X nm flash memories.
