With the wide application of ARM technology, design an interface between ARM and USB-OTG controller which can be used in mobile communication field, PDA, mobile phone and other mobile devices that can exchange data with USB peripherals directly with or without an interaction of PC. Interfacing requires more of AHB protocol defining Bus interconnection, control signals, address decoding. Primarily this paper is focused on discussing methodology and approach to interface ARM with OTG controller and to understand the communication between OTG controller and a number of devices having dual role capability. Secondly paper also covers Advanced Microcontroller Bus Architecture and USB architecture with software programming of USB in both A (Host) and B (Device) mode. Finally, an ARM based interface with USB controller having software capabilities can be used to communicate with wide range of devices like Mobile, Printer etc without PC interaction.
