多串口扩展芯片广泛应用于各种多路通信、数据采集场合，它弥补了一般 MCU串口数

量少的不足，扩展了处理器的串口通道，使得处理器能与更多的串口设备进行通信。本方案

采用 Actel Flash 架构的 FPGA 实现扩展多路串口功能，并通过 FPGA 灵活的结构来为用户

定制不同的功能，可以广泛应用于工业控制、智能家居以及其他需要多路串口的场合，该方

案已经被多家公司采纳。 -Multi-serial port expansion chip is widely applied in various multiplexed communication, data acquisition, which compensates for the serial number commonly MCU

Quantity is little, expand the processor s serial passage, with more serial processor can communicate equipments. This plan

Using Actel Flash architecture FPGA realizing multi-way expansion, and through FPGA serial function for users of flexible structure

Customize different function, can be widely applied in industrial control, intelligent household and other needs more road, the serial port

Case has been adopted by many companies.
