Abstract: A SOC includes a core, peripherals, and a bus for interconnecting the core and peripherals. Some peripherals can be selectively enabled or disabled on-demand. The SoC further includes peripheral enabling/disabling electronics and peripheral enabling/disabling circuitry coupled to the peripherals. The peripheral enabling/disabling electronics are directly connected to the peripheral enabling/disabling circuitry and are configured to store information items related to an enabled/disabled peripheral configuration, indicate the peripherals that are enabled and the peripherals that are disabled according to the enabled/disabled peripheral configuration, and provide the peripheral enabling/disabling circuitry with signals based on the stored information items. The peripheral enabling/disabling circuitry allows operation of the enabled peripherals and prevents operation of the disabled peripherals based on the signals received from the peripheral enabling/disabling electronics. The peripheral enabling/disabling electronics implement a secure mechanism allowing access to the peripheral enabling/disabling electronics and modification of the stored information items if security criteria are met.

Abstract: Method of operating a radio communication system during a stand-by time interval in a stand-by state. The method comprises: applying clock division processing to a reference clock signal and producing a divided clock signal; applying PLL processing to the divided clock signal producing a PLL clock signal; receiving at least one input signal; when the input signal has a first logic value, interrupting applying PLL processing to the divided clock signal and enabling counting clock signal edges of the divided clock signal; when said counting clock signal edges reaches a first target count value, restarting applying PLL processing; continuing counting clock signal edges until reaching a second target count value; when said counting reaches the second target count value, issuing and sampling an end-count signal based on the PLL clock signal, producing a timing clock signal as a result and providing the timing clock signal to a user circuit.

Abstract: A reset pad circuit has first and second inputs coupled, respectively, to a first reset access port receiving a first reset request and a second reset access port. The reset pad circuit generates a first reset state signal. An internal reset activation gate has inputs coupled to internal resources and an output that applies a reset request to the second reset access port. A memory element has first and second inputs coupled, respectively, to the output of the reset activation gate and the output of the reset pad circuit. The memory element generates a second reset state signal when receiving the reset request until receiving the first reset state signal. A reset forward gate coupled to outputs of the reset pad circuit and the memory element generates a system reset request in response to the first reset state signal or the second state signal.

Abstract: A resettable digital stage operates when a supply voltage is higher than a threshold. A non-volatile memory stores a digital code read by a reading stage. A main power-on reset circuit generates a main reset signal controlling reset of the reading stage. A resettable volatile memory coupled to the reading stage stores a default value when reset. An auxiliary power-on reset circuit generates an auxiliary reset signal controlling reset of the volatile memory. Upon deactivation of the reset, the reading stage loads the digital code into the volatile memory. The main power-on reset circuit functions in a non-trimmed configuration response to the stored default value and in a trimmed configuration responsive to the stored digital code. The main power-on reset circuit has first and second operative thresholds which respectively fall within a first and second non-trimmed voltage range or within a first and second trimmed voltage range.

Abstract: An electronic device includes at least two electronic components. A reset circuit includes: a parity control circuit; at least two first flip-flops, wherein each first flip-flop has an output coupled to at least one of the at least two electronic components; and at least two second flip-flops, wherein each second flip-flop has at least one output coupled to an input of the parity control circuit.
