摘要
I2C串行总线是近几年来微处理器领域出现的新技术。由于具有诸多优点,I2C串行总线应用越来越广泛。在介绍了具有I2C总线接口的EEPROM 24LC32特点的基础上,阐述了其I2C总线操作规程、工作原理,包括I2C总线上设备的选择、数据的随机读取和当前地址读取、数据的字节模式写入和页模式写入,给出了24LC32与单片机80C196的接口方式及在智能型热过载继电器中的应用。
The I^2C bus is a serial communication bus, which has been developed in recent years in the microcontroller area. Its applicable areas are more and more due to its many advantages. The features of I^2C EEPROM 24LC32 were described simply in this paper, the bus characteristics and operation rules of I^2C EEPROM 24LC32 were narrated in detail, including the selection of 24LC32 device on the I^2C-bus, random read and current read, byte write and page write. The interface circuit between 24LC32 and 80C196 was presented, and it has been applied in the intelligent thermal relay.
