Abstract

The invention discloses a low-power-consumption chip architecture system with multiple wake-up source inputs. The low-power-consumption chip architecture system comprises a power management circuit, awake-up logic circuit, a timing detection circuit, a low-frequency clock, a main circuit, a clock selector and a high-frequency ring oscillator, the power supply management circuit is used for controlling the power supply input of each circuit to open or close; the wake-up logic circuit is used for acquiring a wake-up signal sent by the timing detection circuit module and sending a correspondingcontrol signal to the power supply management circuit; the timing detection circuit is used for detecting an external wake-up signal to judge a trigger action and sending the wake-up signal to the wake-up logic circuit; the low-frequency clock circuit is used for providing a working clock for the awakening logic circuit and the timing detection circuit; wherein the main circuit is used for processing data and is connected with the awakening logic circuit through a communication port; the clock selector is used for selecting a high-frequency ring oscillator or an external crystal oscillator clock as a clock input into the main circuit; and the high-frequency ring oscillation circuit is used for providing frequencies of multiple gears for the main circuit to use.

Description

technical field [0001] The invention relates to the field of low power consumption circuits, in particular to a low power consumption chip architecture system with multiple wake-up source inputs and a quick start method. Background technique [0002] With the continuous development of smart locks, it is no longer limited to one way to open the door, and gradually develops in the direction of the coexistence of multiple door opening methods, such as the simultaneous support of button password opening, RFID card swiping, fingerprint recognition, and face recognition. Wait. If the functional circuits implemented by each door opening method are to be integrated into one chip, it is necessary to meet all the design requirements of various functional circuits, and it is necessary to consider that the chip can selectively turn off unnecessary ones in different application scenarios. functional circuit. Different door opening methods have different design requirements for chip des...
