ABSTRACT:
An apparatus and method in a mobile device having a digital application-specific integrated circuit (DASIC) and a multifunctional integrated circuit (chip) providing additional functions to the mobile device. An internal Universal Serial Bus (USB) link connects the DASIC and the multifunctional chip. In one embodiment, the multifunctional chip is an ultra wideband (UWB) Radio Module. The internal USB link may utilize a USB interface, a USB 2.0 Universal Transceiver Macrocell Interface (UMTI+) and Low Pin Interface (ULPI), or a High Speed InterChip (HSIC) interface. The UWB Radio Module communicates over the air with an external remote wireless device such as a wireless USB Host utilizing a UWB radio link. The internal USB link provides connection and maps logical data streams in the DASIC with logical data streams in the UWB Radio Module or multifunctional integrated circuit.
