When the fingerprint sensing device senses a fingerprint to generate a fingerprint frame data, the controller enters a sleep mode, and when the controller reads the fingerprint frame data, the fingerprint sensing device stops sensing the fingerprint. Since operations of sensing the fingerprint and reading the fingerprint frame data do not occur at the same time, the high current condition can be avoided so as to decrease power consumption.

At least one transistor of each driving signal output unit and multiple transistors of the memory are fabricated by an identical semiconductor fabrication process so that the gate oxide layers of the transistors of the driving signal output unit and the memory are identical in thickness. As the transistor of each driving signal output unit and those of the memory are fabricated by a same high-voltage semiconductor fabrication process, the transistor of each driving signal output unit can be fabricated to provide a capacitive touch panel controller having high-voltage driving capability without using any high-voltage fabrication process and increasing the production cost. Due to the high-voltage driving, the SNR and anti-interference capability can be increased.
