Abstract: A semiconductor integrated circuit device includes: a first terminal configured to receive a first voltage; a part of a charge pump circuit configured to output a second voltage obtained by stepping down the first voltage received from the first terminal; at least a part of a linear power supply circuit configured to output a third voltage obtained by stepping down the second voltage received from the charge pump circuit; an internal circuit configured to use the third voltage received from the linear power supply circuit as a power supply voltage; a second terminal configured such that a first end of an external resistor included in the charge pump circuit is connected to the second terminal; and a third terminal configured such that a second end of the external resistor is connected to the third terminal.
