PURPOSE: An apparatus for changing an FPGA(Filed Programmable Gate Array) logic circuit within a terminal device board capable of communicating with a host device is provided to perform a telecommunication to change logic configuration data so as to reduce a maintenance time and a cost. CONSTITUTION: If version information of latest FPGA(Filed Programmable Gate Array) logic configuration data is received from a remote host device(20), an FPGA board(30) compares the received latest version information with version information of existing FPGA logic configuration data. The FPGA board(30) decides whether the existing version information and the latest version information are the same. If so, the FPGA board(30) performs a normal function. If the existing version and the latest version information are not the same, the FPGA board(30) receives latest FPGA logic configuration data through a telecommunication function unit(32), and stores the received data in a memory(33). The FPGA board(30) updates data of an FPGA logic configuration data storage area of a flash memory(36). If a data storage is completed in the flash memory(37), a logic configuration controller(37) generates a control signal, and starts a logic configuration of an FPGA(35).
