SAF1760 Hi-Speed Universal Serial Bus host controller for embedded applications Product data sheet

PublishTime：2020-07-24

The SAF1760 is a Hi-Speed Universal Serial Bus (USB) host controller with a generic processor interface. It integrates one Enhanced Host Controller Interface (EHCI), one Transaction Translator (TT) and three transceivers. The host controller portion of the SAF1760 and the three transceivers comply to Ref. 1 “Universal Serial Bus Specification Rev. 2.0”. The EHCI portion of the SAF1760 is adapted from Ref. 2 “Enhanced Host Controller Interface Specification for Universal Serial Bus Rev. 1.0”.The integrated high-performance Hi-Speed USB transceivers enable the SAF1760 to handle all Hi-Speed USB transfer speed modes: high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s). The three downstream ports allow simultaneous connection of three devices at different speeds (high-speed, full-speed and low-speed).The generic processor interface allows the SAF1760 to be connected to various processors as a memory-mapped resource. The SAF1760 is a slave host: it does not require bus-mastering capabilities of the host system bus. The interface can be configured, ensuring compatibility with a variety of processors. Data transfer can be performed on 16 bits or 32 bits, using Programmed Input/Output (PIO) or Direct Memory Access (DMA) with major control signals configurable as active LOW or active HIGH.Integration of the TT allows connection to full-speed and low-speed devices, without the need of integrating Open Host Controller Interface (OHCI) or Universal Host Controller Interface (UHCI). Instead of dealing with two sets of software drivers, EHCI and OHCI or UHCI, you need to deal with only one set, EHCI, that dramatically reduces software complexity and IC cost.
