| Abstract: | The EEPROM and the Flash are common memory devices. The Flash memory is widely used in various industrial products based on its large capacity and data non-disappearing, which is embedded into many processors. Taking the typical ARM chip AT91FR40162 and the EEPROM chip AT24C01A as examples and combining with the application environment, this paper describes the differences between external EEPROM and on-chip Flash memory, and introduces a method which uses the CPU on-chip Flash memory to store some real-time site data by EEPROM devices. |
