    • The present invention is directed to shorten time required to establish a connection and enable information to be actually transmitted/received in a noncontact IC card adaptable to a plurality of communication methods. A semiconductor integrated circuit device of the invention includes: a single demodulating circuit capable of demodulating an input signal; a plurality of sampling circuits each capable of sampling output signals of the demodulating circuit synchronously with a predetermined clock signal; a plurality of detection circuits capable of detecting headers of output signals of the corresponding sampling circuits; a plurality of processing circuits capable of performing a predetermined data process on the basis of detection results of the corresponding detection circuits; and a communication method determining circuit capable of determining a match to a preset communication method from results of the header detection by the plurality of detection circuits. By performing processes adapted to a plurality of different communication methods in parallel, time required to establish a connection and enable information to be actually transmitted/received is reduced.
    • 本发明旨在缩短建立连接所需的时间,并使信息能够在适用于多种通信方法的非接触式IC卡中实际发送/接收。 本发明的半导体集成电路器件包括:能解调输入信号的单一解调电路; 多个采样电路,每个采样电路能够与预定时钟信号同步地对解调电路的输出信号进行采样; 多个检测电路,能够检测对应的采样电路的输出信号的标题; 多个处理电路,能够根据相应的检测电路的检测结果执行预定的数据处理; 以及通信方法确定电路,其能够根据多个检测电路的头部检测结果来确定与预设通信方法的匹配。 通过并行地进行适应于多种不同的通信方式的处理,减少了建立连接所需的时间和实际发送/接收的信息。
