Abstract: PURPOSE: An apparatus of digital MAC for IEEE 802.15.4 system and a system thereof are provided to perform a MAC(Media Access Control) operation without control from the processor. CONSTITUTION: A frame generating unit(410) generates and outputs a frame based on received data, and a frame analyzing unit(420) analyzes the input frame received through a data bus. The frame analyzing unit generates and outputs a control signal and the transceiving data, and a control unit activates the frame generating unit and/or the frame analyzing unit according to the generated control signal. The control unit transmits the outputted frame or data to a processor according to the operation.
