【应用】USB转串口芯片CH340E用于智能门锁,内置晶振,支持波特率2400-115200bps
为了防止智能门锁突然没电而导致开不了门,厂家一般会设计应急开锁方案。本文就此介绍了沁恒的USB转串口芯片CH340E在智能门锁应急开锁方案中的应用。
在智能门锁系统中,可通过USB接口与USB转串口芯片CH340E连接,串口再和电机驱动器连接,驱动锁内电机转动,从而实现开锁。大致框图如下所示。
CH340E具有如下特点:
1、CH340E已内置晶振,无需再外部设置。
2、支持5V电源电压和3.3V电源电压,可满足大部分的供电场景。
3、单芯片集成式解决方案,减少客户对于USB转串口的程序开发,加快产品的设计。
4、CH340E在市面上相比同类型的产品价格和交期都有优势。
沁恒的CH340系列可提供SOP-16、SOP-8和、SSOP-20以及ESSOP-10、MSOP-10等多种封装,用户可根据自己的需求做选择。
