Abstract
Disclosed in the present invention are a chip port state detection circuit, a chip, and a communication terminal. The chip port state detection circuit, by means of a port detection conversion circuit, converts the state of a port to be detected into a corresponding voltage and respectively outputs same to a first comparator and a second comparator, which, after comparing same with a corresponding input reference voltage, output a logic signal to a chip ID determination circuit to obtain a chip ID corresponding to the state of the chip port to be detected, in order to distinguish multiple identical chips.
