The chip comprises at least one pin and is characterized in that the internal part of the chip is provided with at least one electrostatic protection circuit, the electrostatic protection circuit is used for reducing or eliminating damages imposed on other components or circuits inside the chip by static electricity, the electrostatic protection circuit is set corresponding to one of the pins, and the electrostatic protection circuit is electrically connected with the pin. The electronic device comprises the chip provided by the invention.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a chip and an electronic device. Background technique [0002] Static electricity is an objectively existing natural phenomenon, which can be produced in many ways, such as contact, friction, induction between electrical appliances, etc. Static electricity is characterized by long-term accumulation, high voltage, low power, small current and short action time. The action of the human body or the contact, separation, friction or induction with other objects can generate thousands of volts or even tens of thousands of volts of static electricity. Frictional electrification and human body static electricity are two major hazards in the electronics industry, which often cause the chip in the electronic device to run unstable or even be damaged, resulting in poor quality of the electronic device. Contents of the invention [0003] The present invention provides a chip, the chip includes...
