PL-2571
Hi-Speed USB to SATAII Bridge Controller
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.
