An integrated circuit for a multi-function handheld device includes a host interface, a bus, a processing module, a memory interface, a multimedia module, and a DC-to-DC converter. The host interface is operable to receive or transmit data with a host device when the multi-function handheld device is operably coupled to the host device. The processing module functions to place the multi-function handheld device in a first functional mode when the host interface is operably coupled to the host device and places the multi-function handheld device in a second functional mode when the host interface is not operably coupled to the host device. The memory interface is operably coupled to, when the multi-function handheld device is in the first functional mode, provide data received from the host device to memory for storage. The memory interface also provides data retrieved from the memory to the host interface for transmission to the host device. The multimedia module is operably coupled to, when the multi-function handheld device is in the second functional mode, to convert data stored in the memory into rendered output data.
