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.
