Reset circuitry for an integrated circuit

摘要

Reset circuitry for an integrated circuit is presented. An internal oscillator produces an oscillating signal upon power-up of the integrated circuit. The internal oscillator is not dependent on signals generated outside the integrated circuit. An electro-static discharge blocker circuit receives an external reset signal generated outside the integrated circuit. The electrostatic discharge blocker circuit utilizes the oscillating signal to perform electro-static discharge blocking for the external reset signal to produce an internal reset signal.
