Abstract: In one embodiment, an apparatus for peripheral device connection using a Serial Peripheral Interface (SPI) in a portable terminal is provided and a method for data transmission using the same. The apparatus includes an SPI controller for activating each of slaves by independently assigning at least one serial data line to each of the slaves that reads/writes data from/to each of the slaves through at least one serial control line, a slave unit including at least one slave which under the control of the SPI controller, reads out data from the buffer and then performs data transmission between the slaves, and a buffer for temporarily storing the data to be transmitted in order to transmit data between the slaves which may have different data processing speeds and different data transmission speeds.

Abstract: Disclosed is a radio modem terminal for mobile communication, comprising a main body having a functional unit for voice communication; a power supply unit hinged at one side of the main body; and a display unit disposed between the power supply unit and the main body, and also hinged with respect to the power supply unit and the main body to form a foldable type mobile communication device. When the radio modem terminal is not connected to a notebook computer, it can be used as a mobile communication terminal, using a power supply unit as its primary power source. However, if the radio modem terminal is connected to the notebook computer, it functions as the PC card, and uses power from the notebook computer as its primary source of power. Accordingly, the radio modem terminal is conveniently transported and used.
