Abstract
A configuration circuit of a flash FPGA for realizing external monitoring and configuration is provided. In the configuration circuit, a positive high-voltage output terminal of a positive high-voltage charge pump is connected to a positive high-voltage external monitoring port through a positive high-voltage bidirectional switch circuit, and the positive high-voltage output terminal of a positive high-voltage charge pump is further configured as a positive output end of a voltage supply circuit. A negative high-voltage output terminal of a negative high-voltage charge pump is connected to a negative high-voltage external monitoring port through a negative high-voltage bidirectional switch circuit, and the negative high-voltage output terminal of a negative high-voltage charge pump is further configured as a negative output end of the voltage supply circuit. Based on a received mode adjustment signal, a mode control circuit controls to enter an external monitoring mode or an external configuration mode.
