OVERVIEW

The PL-2571 is a single chip Hi-Speed USB-to-SATA bridge controller that is designed to perform seamless

protocol transfer between the USB and SATA interface.

The PL-2571 can also automatically detect and switch between 1.5GHz and 3GHz SATA speed to support

broad range of Serial ATA devices. A high performance 8-bit microcontroller is embedded which can be used

to support versatile system applications such as one button backup, power control, and others. It is also very

easy to upgrade or change the internal firmware through USB interface for different applications or function

upgrade by using an external EEPROM or SPI Flash. The PL-2571 is implemented according to the USB

Bulk-Only Mass Storage Class specification ver1.0. The USB mass storage driver is integrated in most OSes

so no additional driver is needed.
