The data acquisition circuit during a first mode converts analog signals from analog filters into a serial signal and converts the serial signal into a digital signal, and filters the digital signal after converting the digital signal into parallel signals. The data acquisition circuit during a second mode converts the analog signals from the amplifiers into the serial signal and converts the serial signal into the digital signal, outputs the digital signal to the digital chopper circuit, and filters the digital signal after converting the digital signal from the digital chopper circuit into parallel signals. Thus, biological information in the plurality of frequency bands can be appropriately acquired.

The controller transfers data received from outside to the first buffer, and outputs a trigger signal based on the transfer of a predetermined amount of data to the first buffer. The processor transmits a write command to the memory based on receiving the trigger signal. Thus, even in a case where one of memories having various command specifications is implemented in the data processing device, the data can be written into the memory while reducing an increase in power consumption of the processor.
