Patent ID: 8791749

Claim:
A semiconductor integrated circuit provided on a single semiconductor chip, the semiconductor integrated circuit comprising: an external power supply interconnect through which external power supplied from outside the semiconductor chip is transferred; a power generation block including a charge pump circuit, and configured to generate internal power by the charge pump circuit based on the external power and output, at an output of the power generation block, the generated internal power, the internal power having a different power supply voltage from the external power; a power supply control block configured to control the power generation block; a circuit block configured to operate with the internal power; a first power supply interconnect branching off from the external power supply interconnect, and connected to an input of the power generation block, the power generation block receiving, at the input of the power generation block, the external power via the first power supply interconnect; a second power supply interconnect branching off from the external power supply interconnect, and connected to an input of the power supply control block, the power supply control block receiving, at the input of the power supply control block, the external power via the second power supply interconnect; and a filter section provided on the second power supply interconnect and disposed between the external power supply interconnect and the input of the power supply control block, and configured to remove noise propagating through the second power supply interconnect, wherein: the filter section includes: a resistor inserted in the second power supply interconnect; and a capacitor connected between the second power supply interconnect and ground, and a first terminal of the capacitor is directly connected to a connection point between the resistor and the power supply control block, and a second terminal of the capacitor is connected to the ground.
