2.0 Product 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 interface.
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 it connected to. The PIO mode 0 to mode 4,
Multi Word DMA mode 0 to mode 2, and Ultra DMA mode 0 to mode 6 are implemented to support
difference IDE devices. The chip will negotiate with 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 ver1.0.
While the driver is default supported by most the OS so that no additional driver is needed for the
bridge function.
