ISP1760
Hi-Speed Universal Serial Bus host controller for embedded
applications
Rev. 01 — 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 Specification Rev. 2.0.
The EHCI portion of the ISP1760 is adapted from Enhanced Host Controller Interface
Specification 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 ‘bus-mastering’ capabilities of the host system bus. The interface is configurable,
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.
2. Features
s The Host Controller portion of the ISP1760 complies with Universal Serial Bus
Specification Rev. 2.0
s The EHCI portion of the ISP1760 is adapted from Enhanced Host Controller Interface
Specification for Universal Serial Bus Rev. 1.0
s Contains three integrated Hi-Speed transceivers that support the high-speed,
full-speed and low-speed modes
s Integrates a TT for Original USB (full-speed and low-speed) device support
s Up to 64-kbyte internal memory (8 k x 64 bits) accessible through a generic processor
interface; operation in multitasking environments is made possible by the
implementation of virtual segmentation mechanism with bank switching on task
request
