Zusammenfassung:The invention provides an electrostatic discharge protection module and a device using the same. The electrostatic discharge protection module comprises an RC detection unit and a silicon controlled rectifier unit which are connected between a first potential and a second potential, wherein the RC detection unit is used for generating a first signal and a second signal; an SCR unit is used for receiving the first signal and the second signal generated by the RC detection unit; specifically, the SCR unit further comprises a protection unit which is controlled by the first signal or the second signal output by the RC detection unit; during electrostatic discharge, the first signal generated by the RC detection unit is low level, the second signal generated by the RC detection unit is high level, the protection unit is controlled to be in a low-resistance state, the SCR unit works, a P-N-P-N path is formed, and a first current release path is provided for electrostatic current; when the circuit works normally, t
