Abstract: A data protection circuit of a chip, a chip, and an electronic device, where the data protection circuit performs bit width expansion and scrambling processing on a first alarm signal using an operation circuit to obtain a second alarm signal, and outputs the second alarm signal to a processing circuit. The processing circuit performs descrambling processing after receiving the second alarm signal to obtain a descrambling result. When the second alarm signal is attacked, the descrambling fails, and the descrambling result is an active level. The processing circuit outputs the descrambling result to a reset request circuit, and the reset request circuit generates a reset request signal according to the descrambling result.
