I2 BUS and Flash Microcontroller are introduced and the principle and method of the application of I2C BUS to data collection system are investigated. The structure of I2C BUS is described and the dala transfer on I'C BUS is analyzed in detail. BY an example, the implementation schemes of connect the serial H2PROM to the Flash Microcontroller is proposed. The design of hardware is directly facing AT89C2051 Flash Microcontroller of the series of AT89, and the serial K2PROM can be substituted with the AT24C16. The research proves lhat the application of I'C BUS to data collection system has expediently, agile, high efficiency and feasible. I'C BUS is applies to the different applications widely. The content inlnxluced by this article is valuable for the application of I'C BUS.
