Problems solved by technology

[0005] However, when the FPGA is configured in the MCU chip, using a piece of EPROM or a piece of PROM to program the FPGA will increase additional costs, and the area of ​​the MCU chip will increase accordingly, further increasing the cost. For programmable devices, the corresponding data information is lost after power failure, causing the FPGA to not work normally
