General description
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.
