| Abstract: | This article introduced a serial EEPROM chip X84041 in the SCM with supervisory and measure control system, solved the long-term dependable conservancy of important parameter, but encapsulation of value needs a programming method of being altered more conveniently. Based on the research into the char- acteristics and work principle of the chip, a interface electric circuit practically is designed, and the electric circuit is briefly described, finally giving an interface electric circuit and program for hardware. The experi- ment proved that the kind of electric circuit removed the need of pin and converter from the serial to the parallel, having lowered its cost and excellent performance. |
