ISP1760
Hi-Speed Universal Serial Bus host controller for embedded
applications
Rev. 01 鈥?8 November 2004
Product data sheet
1. General description
The ISP1760 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
ISP1760 and the three transceivers comply to
Universal Serial Bus Speci鏗乧ation Rev. 2.0.
The EHCI portion of the ISP1760 is adapted from
Enhanced Host Controller Interface
Speci鏗乧ation for Universal Serial Bus Rev. 1.0.
The integrated high-performance Hi-Speed USB transceivers enable the ISP1760 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 ISP1760 to be connected to various
processors as a memory-mapped resource. The ISP1760 is a slave host: it does not
require 鈥榖us-mastering鈥?capabilities of the host system bus. The interface is con鏗乬urable,
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 con鏗乬urable 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鈥擡HCI and OHCI or
UHCI鈥攜ou need to deal with only one set鈥擡HCI鈥攖hat dramatically reduces software
complexity and IC cost.
