USB On-The-Go Dual Role Controllers, ISP1362

ISP1362

General Description

The ISP1362 is a single-chip Universal Serial Bus (USB) On-The-Go (OTG) controller integrated with our advanced slave USB host controller and our ISP1181B peripheral controller. The USB OTG Controller is compliant with On-The-Go Supplement to the USB 2.0 Specification Rev. 1.0a. The host and peripheral controllers are compliant with Universal Serial Bus Specification Rev. 2.0 (full-speed and low-speed support only), 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 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 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.

Key Features

Universal Serial Bus Specification Rev. 2.0
On-The-Go Supplement to the USB 2.0 Specification Rev. 1.0a

Supports data transfer at full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s)

Adapted from Open Host Controller Interface Specification for USB Release 1.0a

USB OTG:

Supports Host Negotiation Protocol (HNP) and Session Request Protocol (SRP) for OTG dual-role devices
Provides status and control signals for software implementation of HNP and SRP
Provides programmable timers required for HNP and SRP

Applications

The ISP1362 can be used to implement a dual-role USB device in any application, USB host or USB peripheral, depending on the cable connection. If the dual-role device is connected to a typical USB peripheral, it behaves like a typical USB host. The dual-role device, however, can also be connected to a PC or any other USB host and behave like a typical USB peripheral.
