ISP1161A1
Universal Serial Bus single-chip host and device controller
Rev. 03 — 23 December 2004
Product data
1. General description
The ISP1161A1 is a single-chip Universal Serial Bus (USB) Host Controller (HC) and
Device Controller (DC). The Host Controller portion of the ISP1161A1 complies with
Universal Serial Bus Specification Rev. 2.0,
supporting data transfer at full-speed
(12 Mbit/s) and low-speed (1.5 Mbit/s). The Device Controller portion of the
ISP1161A1 also complies with
Universal Serial Bus Specification Rev. 2.0,
supporting data transfer at full-speed (12 Mbit/s). These two USB controllers, the HC
and the DC, share the same microprocessor bus interface. They have the same data
bus, but different I/O locations. They also have separate interrupt request output pins,
separate DMA channels that include separate DMA request output pins and DMA
acknowledge input pins. This makes it possible for a microprocessor to control both
the USB HC and the USB DC at the same time.
The ISP1161A1 provides two downstream ports for the USB HC and one upstream
port for the USB DC. Each downstream port has an overcurrent (OC) detection input
pin and power supply switching control output pin. The upstream port has a V
BUS
detection input pin.The ISP1161A1 also provides separate wake-up input pins and
suspended status output pins for the USB HC and the USB DC, respectively. This
makes power management flexible. The downstream ports for the HC can be
connected with any USB compliant devices and hubs that have USB upstream ports.
The upstream port for the DC can be connected to any USB compliant USB host and
USB hubs that have USB downstream ports.
The HC is adapted from the
Open Host Controller Interface Specification for USB
Release 1.0a,
referred to as OHCI in the rest of this document.
The DC is compliant with most USB device class specifications such as Imaging
Class, Mass Storage Devices, Communication Devices, Printing Devices and Human
Interface Devices.
The ISP1161A1 is well suited for embedded systems and portable devices that
require a USB host only, a USB device only, or a combination of a configurable USB
host and USB device. The ISP1161A1 brings high flexibility to the systems that have
it built-in. For example, a system that uses an ISP1161A1 allows it not only to be
connected to a PC or USB hub with a USB downstream port, but also to be
connected to a device that has a USB upstream port such as a USB printer, USB
camera, USB keyboard or a USB mouse. Therefore, the ISP1161A1 enables
point-to-point connectivity between embedded systems. An interesting application
example is to connect an ISP1161A1 HC with an ISP1161A1 DC.
Consider an example of an ISP1161A1 being used in a Digital Still Camera (DSC)
design.

USB HC and a USB DC at the same time.
