PL-2571B Hi-Speed USB-to-SATA Bridge Controller LQFP48

The PL-2571B 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-2571B 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-2571B 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.
