The X25043/45 chip produced by Xicor cooperation in America, integrates the system resetting circuit, watchdog circuit and E2PROM register, and it?s very powerful in function. The paper introduced the characteristic, principle and using method of the X25043/45, and it is applied in the industry temperature gauges, makes the temperature gauge to have the function of memory and adjusting by itself so that it is upgraded to be a temperature control. Furthermore, the typical method of implementing by software is given, its life is increased. The use of other types of E2PROM is similar to this one, so that they can be used by referring to the paper.
