Hi-Speed Universal Serial Bus host controller for embedded applications

Integrating one Enhanced Host Controller Interface (EHCI), one Transaction Translator (TT) and three transceivers, the SAF1760 is a Hi-Speed Universal Serial Bus (USB) host controller with a generic processor interface. The EHCI portion of the SAF1760 is adapted from Enhanced Host Controller Interface Specification for Universal Serial Bus Rev. 1.0.

For being a slave host, the SAF1760 does not require bus-mastering capabilities of the host system bus. The interface can be configured which ensures compatibility with a variety of processors. Using Programmed Input/Output (PIO) or Direct memory Access (DMA), data transfer can be performed on 16 bits or 32 bits with major control signals configurable as active LOW or active HIGH.
