    Abstract: Systems and methods for scanning and characterizing an integrated circuit for transient events. Embedded apparatus can detect transient events that may be incident on the integrated circuit, and moreover, identify particular nodes of the integrated circuit that are affected by the transient event. Additionally, the integrated circuit can be characterized by applying known transient pulses of varying severity to selected nodes of the integrated circuit, detecting the severity levels at which the selected nodes can fail, and storing indications pertaining to pulse severity at which selected nodes can fail. Moreover, based on the characterization, targeted protection mechanisms can be provided for nodes that are characterized as being susceptible.

    Abstract: A semiconductor device is described that includes one or more electrostatic discharge (ESD) protection circuits. Each circuit comprises reverse-biased steering diodes connected in series between power rail and signal ground, a bypass Zener diode and a substrate Zener diode. The Zener diodes provide ESD protection and the steering diode cooperate with the substrate Zener diode to provide a bypass function that is substantially symmetric about the signal ground. Noise in the circuit can be shunted using internal and/or external capacitances that can be implemented as Zener diodes.

    Abstract: A programmable timer is disclosed for use in conjunction with a microcontroller circuit. The timer is used as part of a time slice arbiter in a real time operating system, which arbiter manages device routines by allocating them to distinct code time slices executable by such microcontroller. The set up of time slices, including their number, sequence, duration, etc., can be configured and optimized to achieve a desired system performance level based on characteristics of an associated system bus, devices on the bus, etc. The timer operates as a hardware controller to direct the interrupt handler to various entry points in the corresponding routines associated with interrupt based devices on a system bus.
