A controller chip includes a first cluster including one or more first controller units, a first power supply grid, a first clock tree structure to supply one or more clock signals, and at least a first power supply input. A second cluster includes one or more second controller units, a second power supply grid, a second clock tree structure to supply one or more clock signals, and at least a second power supply input. A monitoring cluster includes a monitoring circuit configured to: monitor the power supply and the clock signal supply of each of the first cluster and second cluster, and in the event of determining at least one of a power supply failure or a clock signal supply failure in one cluster of the first cluster or the second cluster, indicate the failure to the other cluster to take one or more actions.

Systems, devices, and methods for controller devices handling fault events

Systems, methods, and circuitries are provided for controlling a microcontroller (MCU) on a per-application basis. A control system includes a microcontroller unit (MCU) including a first application group and a second application group. The first application group includes at least one hardware component not associated with the second application group. The control system includes a power management integrated circuit (PMIC). The PMIC includes monitoring circuitry configured to monitor the first application group to detect a first application group fault condition and monitor the second application group to detect a second application group fault condition. Based on the monitoring, the PMIC provides a first reset signal to the first application group that does not reset the second application group or provides a second reset signal to the second application group that does not reset the first application group.
