Abstract
An integrated circuit includes a comparator circuit that generates a control signal based on a comparison between a threshold voltage and a supply voltage. The integrated circuit also includes a clock signal generation circuit that generates a clock signal and that receives the control signal. The clock signal generation circuit decreases a frequency of the clock signal to a reduced frequency in response to the control signal indicating that the supply voltage has decreased below the threshold voltage. The integrated circuit also includes a secure device manager circuit that has a timing circuit. The clock signal is provided to a clock input of the timing circuit. The timing circuit receives supply current from the supply voltage. The secure device manager circuit performs a security function for the integrated circuit using the timing circuit in response to the clock signal with the reduced frequency.
