Saelig Introduces SuperSpeed USB3.0 to SATAII Bridge Controller

Pittsford, NY, USA:  Saelig Company, Inc. ( has introduced the PL2771 - a single-chip SuperSpeed USB3.0 to SATAII compliant bridge controller that is designed to perform seamless data transfer between USB3.0 and SATAII devices, supporting the latest USB3.0 SuperSpeed 5Gb/s transfer rates. SuperSpeed USB 3.0(5Gb/s) delivers ten times the performance of Hi-Speed USB 2.0(480Mb/s) while offering compatibility with all USB-enabled PCs and peripheral devices - fully backward compatible to all USB 2.0 and USB 1.1 hosts.  PL2771 can operate under SuperSpeed, Hi-Speed, and Full-Speed USB connections. It also contains an internal embedded high performance 8-bit microcontroller that can be used to support versatile system applications such as one button backup, power control, and other features for USB connection. The PL2771 is implemented with a USB Mass Storage Class driver and the latest UASP driver.

Packaged as a 48-pin QFN or 64-pin LQFP device, the PL2771 uses a 30MHz reference clock and is hot-plug Serial ATA Rev.2.6 compliant. Its ultra-low power internal core is designed in 0.13um silicon and runs on 1.2V to keep power consumption to a minimum, although I/O lines operate at 3.3V. Twelve multi-function general purpose I/O (GPIO) pins can be programmed for USB-speed LED, button inputs, or other special functions using the available software development kit. Onboard firmware is upgradeable through the USB interface.  PL2771 also supports a PWM interface and a generic SPI/I2C master/slave interface. 

The PL2771’s internal data buffer optimizes downstream and upstream data transfer performance, and it supports greater than 2-Terabyte/4KB-sector Hard Drives with USB3.0/USB2.0/SATA Power Saving Management.

Target Applications include USB 3.0 external HDD/SSD/ODD, portable media players, SATA port multipliers, etc. and a demonstration board is available for development purposes.

PL2771 is manufactured by Prolific Technology Inc., a leading Taiwan IC design house, and is available now from their USA distributor Saelig Company at under $10 (2K qty). 1-888-7SAELIG
