In the prior art, the aim of completely identifying the wake-up source is fulfilled by upgrading the MCU singlechip platform or adding the SBC, but the mode can increase the cost of upgrading the MCU singlechip platform or increasing the SBC.
Therefore, the invention provides a wake-up source identification method and device, which are used for solving the problem of increasing cost caused by upgrading an MCU single-chip microcomputer platform or adding an SBC module to identify all wake-up sources.

For example, the SBC power management unit includes 3 wake-up source signal detection modules, two wake-up source signals being present in each wake-up source detection module. If the wake-up source signal detection module with the wake-up source signal detection number of 1 comprises a KL15 wake-up source signal and a specific frame wake-up source signal; the wake-up source signal detection module with the wake-up source signal detection number of 2 comprises an RTC wake-up source signal and a CC wake-up source signal; the wake-up source signal detection module with the wake-up source signal detection number of 3 comprises a DC wake-up source signal and a CP wake-up source signal.
It should be noted that, according to the actual situation, the wake-up source signals meeting the conditions may be stored in the same wake-up source detection module.
For example: the wake-up source signal detection module with the wake-up source signal detection number of 1 can comprise a KL15 wake-up source signal and an RTC wake-up source signal. Namely, a KL15 wake-up source signal and a specific frame wake-up source signal are included in the wake-up source signal detection module with the wake-up source signal detection number of 1 but not limited to.

Namely, the analog quantity acquired by the partial analog quantity detection circuit is used for determining a wake-up source to be waken corresponding to the current wake-up source signal meeting the condition.
For example, the number of the wake-up source signal detection module is 1, the corresponding wake-up source signal detection module A comprises KL15 to be detected and a specific frame, and when the analog quantity collected by part of analog quantity detection circuits has the analog quantity of the wake-up source corresponding to the KL15 in the wake-up source signal detection module A meeting the condition, the wake-up source corresponding to the KL15 is determined to be the wake-up source to be waken.
