Abstract: Integrated Circuits (ICs) comprising circuits configured to generate a power on reset (POR) pulse are disclosed. An IC comprises a power supply sense circuit configured to generate a sense signal in response to a transition of a power supply signal from a first level to a second level, and a pulse generation circuit coupled with the power supply sense circuit. The pulse generation circuit is configured to generate a power on reset (POR) pulse of a threshold duration based on the sense signal. The IC further includes a reset generation circuit coupled with the pulse generation circuit to receive the POR pulse. The reset generation circuit is configured to generate a reset pulse based on the POR signal and of at least one control signal, where the reset pulse is configured to be utilized to perform a reset of one or more elements of the integrated circuit.

Abstract: An I/O module configured to operate over a range of voltage supplies includes a transmit path circuit and a receive path circuit that are each configured to convert a data signal between a core voltage domain and one of a first voltage domain (e.g., a high voltage domain) and a second voltage domain (e.g., a low voltage domain) in response to a mode select signal.
