The ISP1362 is a single-chip Universal Serial Bus (USB) On-The-Go (OTG) controller integrated with the advanced Philips Slave Host Controller (PSHC) and the Philips ISP1181B Device Controller (DC). The USB OTG controller is compliant with On-The-Go Supplement to the USB 2.0 Specification Rev. 1.0a. The host and device controllers are compliant 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 ISP1362 has two USB ports: port 1 and port 2. Port 1 can be hardware configured to function as a downstream port, an upstream port or an OTG port whereas port 2 can only be used as a downstream port. The OTG port can switch roles from host to peripheral, or from peripheral to host. The OTG port can become a host through the Host Negotiation Protocol (HNP) as specified in the OTG supplement.

A USB product with OTG capability can function either as a host or as a peripheral.For instance, with this dual-role capability, a Personal Computer (PC) peripheral such as a printer may switch roles from a peripheral to a host for connecting to a digital camera so that the printer can print pictures taken by the camera without using a PC. When a USB product with OTG capability is inactive, the USB interface is turned off. This feature has made OTG a technology well-suited for use in portable devices-such as, Personal Digital Assistant (PDA), Digital Still Camera (DSC) and mobile phone-in which power consumption is a concern. The ISP1362 is an OTG controller designed to perform such functions.
