Abstract
A semiconductor integrated circuit device includes: an inter-equipment authentication section formed on a chip; a control section formed on the chip being capable of giving instructions to stop the oscillation of the oscillation section; and an oscillation stop canceling section configured to output an oscillation stop canceling signal to restart the oscillation of the oscillation section, based upon whether or not 5 volts of DDC from the source equipment is supplied to an input terminal. The start of the operation of a microcontroller unit on a system on chip is cable of being controlled by the 5 volts of DDC, which are power supply voltage supplied from the source equipment via DDCs, to thereby incorporate a data authentication section and the inter-equipment authentication in an integrated circuit without increasing power consumption.
