Title:

ELECTRONIC APPARATUS, IMAGE FORMATION DEVICE, AND POWER SUPPLY CONTROL METHOD FOR ELECTRONIC APPARATUS

Document Type and Number:

Japanese Patent JP2023132600

Kind Code:

A

Abstract:

To generate an appropriate voltage in a power supply generation unit without mediation of a program to be executed by a processor.SOLUTION: An electronic apparatus includes: a processor; a memory that stores a program to be executed by the processor and that operates in synchronization with a clock signal while receiving a clock enable signal of a valid level from the processor; a frequency detection unit that detects a frequency the clock enable signal is set to the valid level; a power supply generation unit that generates a voltage, and sets the voltage when the frequency detected by the frequency detection part is low to be lower than the voltage when the frequency is high; and a function unit that operates with the voltage generated by the power supply generation unit.SELECTED DRAWING: Figure 3
