摘要： A demodulation signal is generated by provision of a demodulation signal generation circuit to the semiconductor device capable of wireless communication and by obtainment of a difference between voltages having opposite polarities by the demodulation signal generation circuit. Alternatively, a plurality of demodulation signal generation circuits and a selective circuit which selects a demodulation signal generation circuit depending on characteristics of a received signal are provided, where operation of a second demodulation signal generation circuit stops when a first demodulation signal generation circuit is operated. The selective circuit includes an inverter circuit, a flip-flop circuit, and a selector circuit. When the second demodulation signal generation circuit has a comparator and the like, power consumption thereof is reduced.

摘要： A command sequence is restarted from the middle even when supply of power supply voltage to an internal circuit in a wireless tag is temporarily stopped (a power flicker occurs). A register or a cache memory included in a signal processing circuit in the wireless tag continues to retain data even after the supply of power supply voltage is stopped. After the power flicker occurs, the signal processing circuit in the wireless tag is returned to the state before the supply of power supply voltage is stopped and can restart signal processing. Consequently, the command sequence can be restarted from the middle.

摘要： When a CPU provided with a latch memory is operated, a constant storage method or an end storage method is selected depending on what is processed by the CPU; thus, the CPU provided with a latch memory has low power consumption. When the CPU provided with a latch memory is operated, in the case where the number of times of turning on and off the power source is high, a constant storage method is employed and in the case where the number of times of turning on and off the power source is low, an end storage method is employed. Whether a constant storage method or an end storage method is selected is determined based on the threshold value set depending on power consumption.
