USB 2.0 Full Speed OTG Controller
Overview
Innovative Logic’s USBFDRC primarily provides a ‘Dual-role’ USB controller for use as either the host or
the peripheral in point-to-point communications with another USB function (which may be either full-speed
or low-speed). Alternatively it can be used as device controller for a full-speed USB peripheral.
It complies with both the USB standard for full-speed functions and the On-The-Go supplement to the USB
2.0 specification. The USB On-The-Go specification has been introduced to provide a low-cost connectivity
solution for consumer portable devices such as mobile phones, PDAs, digital still cameras and MP3 players.
Devices that are solely peripherals initiate transfers through a Session Request Protocol (SRP) while
Dual-role devices support both SRP and Host Negotiation Protocol (HNP).
