First out of the Gate

The PL2771 is the first Prolific USB3.0 based product to be released. As a low-power, single-chip, SuperSpeed USB 3.0 to SATAII compliant bridge controller, PL2771 has been designed to perform seamless protocol transfers between the USB 3.0 host and SATAII interface device.

Speed is a Factor

The PL2771 is capable of data transfer speeds of up to 5Gbps in bandwidth, a 10x performance increase over Hi-Speed USB 2.0 (480Mbps). PL2771 is fully backward compatible to all USB 2.0 and USB 1.1 host/hub controllers and will operate flawlessly in conjunction with any attached USB host/hub connection, regardless of speed.

Performance as the Goal

As part of it's winning design, PL2771 is an embedded high performance 8-bit microcontroller which can be used to support versatile system applications such as one button backup, power control, and a variety of other USB device features.
