  • Low ICC enumeration scheme for bus powered USB device
    Patent number: 5987617
    Abstract: An apparatus and method of reducing power consumption in an integrated device having a first module with a mandatory operating frequency and a second module with a flexible frequency requirement. The integrated device is powered by a serial bus. The first module is segregated from the second module in the time domain by a frequency independent interface. The second module is then operated at a lower frequency when power conservation is needed. The operating frequency of the second module can be dynamically changed to improve performance of the second module when a power budget for the device permits.
