Embedded Universal Serial Bus Host Controller

Rev. 04 — 04 July 2003

Product data

1. General description

The ISP1160 is an embedded Universal Serial Bus (USB) Host Controller (HC) that

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 ISP1160 provides two

downstream ports. Each downstream port has an overcurrent (OC) detection input

pin and power supply switching control output pin. The downstream ports for the HC

can be connected with any USB compliant USB devices and USB hubs that have

USB upstream ports.

The ISP1160 is well suited for embedded systems and portable devices that require a

USB host. The ISP1160 brings high flexibility to the systems that have it built-in. For

example, a system that has the ISP1160 built-in allows it to be connected to a device

that has a USB upstream port, such as a USB printer, USB camera, USB keyboard,

USB mouse, among others.
