摘要:介绍了I2C总线技术,并以AT24CXX系列IC卡为例介绍了基于I2C总线的通用存储器IC卡以及其与不带有I2C技术的单片机的接口技术,给出了相应的读写操作及其所需各种信号的程序,但单片机对不同存储容量的IC卡的读写操作也不完全相同,在程序中给出了很多种读写方式,并以表格的形式详细说明,使得该技术更具通用性.

he I2C BUS-Based on Interface Technology of MCU and General Memory IC Card

Abstract:This paper clearly introduces I2C bus technology, using examples of an AT24CXX series, it states that with an I2C bus based on general- purpose memory IC card and its interface technology with MCU without I2C bus technology;It provides a program list including reading and writing and kinds of signals that are needed with detailed annotations, putting forward a kind of general- purpose technology.However, there are different ways to read or write IC cards that have different capacities.The paper lists many ways to read or write IC cards, and elaborates on these mathods through tables that have more generality.
