USB to Serial / Parallel

PL-2506 Hi-Speed USB to IDE Bridge Controller

The PL-2506 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 4, 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 can communicate with the connected device to select the proper mode to obtain the best performance.
And it is compliant 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.
