Abstract:
A power-up control circuit utilizes on-chip circuits, multiple voltages, a ring oscillator and counter, and edge and level detection circuits to guarantee reset during power-up conditions and continues the reset state with a variable length counter to guarantee a predictable reset. In addition, a clean start-up after a logical power-down condition is provided.
