PL-2507
Hi-Speed USB to IDE Bridge Controller
OVERVIEW
The PL-2507 is a single chip USB2.0-IDE bridge controller, which is designed to perform a seamless protocol transfer
between the USB and ATA interfaces.
It will work with full function at full speed or high speed USB transfer mode. The operating speed mode is determined by
the capability of the host/hub to which it is connected. The PIO mode 0 to mode 5, Multi Word DMA mode 0 to mode 2,
and Ultra DMA mode 0 to mode 4 are implemented to support difference IDE devices. The chip will communicate with the
connected device to select the proper mode to obtain the best performance,
The chip is implemented according to the USB Bulk-Only Mass Storage Class specification ver 1.0. Since the default
driver is supported by most the OS, no additional driver is needed.
