I^2C桥接口电路设计及其ASIC实现

Electronic Design of I^2C Bridge and Its ASIC Implementation

介绍一个从模式I2C桥接口电路,实现了I2C总线与专用集成电路芯片之间的数据交换.它通过在通用的I2C协议上建立系统专用的数据传输协议,完成了不同数据宽度的寄存器寻址读写等复杂操作,同时节省了芯片管脚资源.

Introduces an I^2C bridge interface circuit in slave mode. The circuit realizes data transport between I^2C bus and ASIC. This interface builds a special data transport protocols on I^2C communication, realize a series operations of read/write on registers with different width. Meanwhile it greatly reduces resource of the chip.
