摘要： A power-supply sequence-free electronic circuit is realized without the increase of the number of power supply detectors for detecting the rising of the power supply. The electronic circuit operated by supplying three or more types of power supply voltages to the ground voltage of the circuit generates a first detection signal indicating whether any one of other power supply voltages does not rise by a first detection circuit which is operated with a predetermined power supply voltage as an operation power supply. The electronic circuit generates a second detection signal indicating whether the predetermined power supply voltage rises by a second detection circuit which is provided for each of the other power supply voltages and operated with one power supply voltage of the other power supply voltages as an operation power supply. The electronic circuit generates a control signal for ensuring the rising of other power supply voltages for each of the other power supply voltages based on the first and second detection signals.

摘要： Efficient reduction in power consumption is achieved by combinational implementation of a power cutoff circuit technique using power supply switch control and a DVFS technique for low power consumption. A power supply switch section fed with power supply voltage, a circuit block in which a power cutoff is performed by the power supply switch section, and a level shifter are formed in a DEEP-NWELL region formed over a semiconductor substrate. Another power supply switch section fed with another power supply voltage, a circuit block in which a power cutoff is performed by the power supply switch section, and a level shifter are formed in another DEEP-NWELL region formed over the semiconductor substrate. In this arrangement, there arises no possibility of short-circuiting between different power supplies via each DEEP-NWELL region formed over the semiconductor substrate.

摘要： The present invention is directed to perform fine low-voltage control without largely increasing the circuit layout area in a low-power consumption structure. In the case of shifting a region to a low-speed mode, a system controller outputs a request signal and an enable signal to a power switch controller and a low-power drive circuit, respectively, to turn off a power switch and to perform a control so that the voltage level of a virtual reference potential becomes about 0.2 V to about 0.3V. The region operates on voltages between a power supply voltage and a virtual reference potential, so that it is controlled in the low-speed mode.
