Patent number: 10317978Abstract: A microcontroller is operable in a low-power mode and includes one or more I/O connectors, as well as an I/O controller operable to provide control signals for controlling a state of a particular one of the I/O connectors. The I/O controller is powered off or deactivated during the low-power mode. The microcontroller also includes I/O connector state control logic operable to control the state of the particular one of the I/O connectors in accordance with the control signals from the I/O controller. The I/O connector state control logic includes I/O connector state retention logic that retains states of the control signals and maintains the particular I/O connector in a corresponding state in accordance with the retained control signals while the microcontroller is in the low-power mode.Type: GrantFiled: December 5, 2016Date of Patent: June 11, 2019Assignee: Atmel CorporationInventors: Sebastien Jouin, Romain Oddoart, Patrice Menard, Mickael Le Dily, Thierry Gourbilleau

Patent number: 10228752Abstract: A voltage scaling system can scale a supply voltage while preventing processor access of system components that are rendered unstable from the scaling. A processor receives an instruction to scale a system supply voltage to a target supply voltage. The processor executes the instruction and enters into a sleep mode. The processor can send, to a controller that saves power, an indication that the processor is in the sleep mode. When the processor is in the sleep mode, the processor becomes inactive and cannot access any components, e.g., Flash memory data, of the voltage scaling system. The controller can configure a voltage regulator to scale the system supply voltage to the target supply voltage. Once the target supply voltage is reached, the voltage regulator sends an interrupt to the processor, thereby waking up the processor from the sleep mode.Type: GrantFiled: March 28, 2016Date of Patent: March 12, 2019Assignee: Atmel CorporationInventors: Sebastien Jouin, Romain Oddoart, Patrice Menard, Mickael Le Dily, Thierry Gourbilleau

Patent number: 9317095Abstract: A voltage scaling system can scale a supply voltage while preventing a processor from communicating with first system components that are rendered unstable from the scaling. On the other hand, the voltage scaling system allows second system components that are stable during the scaling to communicate with the processor. A processor scales a system supply voltage to a target supply voltage. The processor halts operations of the first system components and executes the instruction. When the first system components are halted, the processor cannot access the first system components. The second system components can continue operating during the scaling. A controller that saves power can configure a voltage regulator to scale the system supply voltage to the target supply voltage. Once the target supply voltage is reached, the voltage regulator sends an indication to a power management unit, after which the first system components continue to operate.Type: GrantFiled: September 13, 2012Date of Patent: April 19, 2016Assignee: Atmel CorporationInventors: Sebastien Jouin, Romain Oddoart, Patrice Menard, Mickael Le Dily, Thierry Gourbilleau
