USB On-The-Go Dual Role Controllers

ISP1761/ISP1763A is a Hi-Speed USB dual-role (host/peripheral) controller with built-in support for USB On-The-Go (OTG), the USB extension that enables point-to-point communications between portable devices. Combining the standard host function with USB OTG capability makes for a very flexible solution, allowing a portable device such as a mobile phone, a DVC, a DSC, or a PDA to support any USB-enabled peripheral, including keychain storage devices.

Unlike a traditional host, an OTG dual-role device has limited host capability. It is not required to support some of the functions of a traditional USB PC/host and is not required to be capable of hosting all possible types of USB devices. The OTG dual-role device manufacturer may choose which devices or classes of devices the dual-role product will support when acting as the host. The details of these supported peripherals are maintained in the device's targeted peripheral list.

If you do not require a Hi-Speed USB-capable dual-role or OTG solution, we have ISP1161A1 and ISP1362 to address your needs. They support data transfer rates 12 Mbit/s and 1.5 Mbit/s.
