A semiconductor integrated circuit includes a CPU core unit, an on-chip-bus unit coupled to the CPU core unit, a on-chip memory directly connected to the on-chip-bus unit, and a voltage controlling unit configured to control a power supply voltage for driving the CPU core circuit and to output a boot switch signal, the on-chip-bus unit configured to switch a boot address between the memory and another device in response to a state of the boot switch signal when the CPU core unit fetches boot program instructions from the boot address.
