XR21V1410

1频道全速USB UART

Description

XR21V1414是一种增强型4通道通用异步接收器和发射器( UART)与一个USB接口。 USB接口完全符合全速USB 2.0规格,支持12Mbps的USB数据传输速率。 USB接口还支持USB暂停,恢复及远程唤醒行动。

XR21V1414的运作是透过内部的48MHz时钟,因此不需要外接晶体/振荡器就像上一代个UART 。随着局部波特率发生器,任何波特率可以准确地使用内部的48MHz时钟。

大的128字节发送FIFO ,以及384字节的接收FIFO的XR21V1414有助于优化整体数据吞吐量为各种应用。自动收发方向控制功能,简化了硬件和软件的半双工RS - 485应用。在多点( 9位)模式下自动半双工收发器控制功能进一步简化了典型的多点RS - 485接口的应用。

XR21V1414的运作是从单一2.97至3.63伏的电源供应器和5V宽的输入。
Windows 2000 , XP , Vista以及Linux和Mac的虚拟COM端口驱动程式都可用于XR21V1414。
