摘　　要：为加强I^(2)C(Inter-Integrated Circuit)总线控制器的IP(Intellectual Property)复用性和IP应用广泛性,设计了一种低功耗I^(2)C总线控制器。该总线控制器集成于MCU(Microcontroller Unit)系统中,不仅能够满足I^(2)C总线协议进行数据通信,而且能够唤醒处于低功耗模式的系统,使芯片恢复正常工作。对采用的低功耗技术、I^(2)C的通信功能和低功耗功能的设计与实现进行了介绍。对设计的I^(2)C总线控制器进行了系统仿真,分析表明该设计实现了I^(2)C总线协议的通信,并能够唤醒低功耗系统,满足设计预期。To enhance the IP reusability and applicability of the I^(2)C bus controller,this paper presents the design of a low-power I^(2)C bus controller.This bus controller is integrated into the MCU system,not only meeting the I^(2)C bus protocol for communications but also capable of waking up systems in low-power modes,allowing the chip to resume normal operation.The paper introduces the low-power techniques adopted,along with the design and implementation of the I^(2)C communication and low-power functionalities.System simulations of the designed I^(2)C bus controller demonstrate successful implementation of the I^(2)C bus protocol for communication and the ability to wake up low-power systems,meeting the design expectations.
