亞信電子提醒您  
親愛的客戶您好:

假如在使用亞信USB轉乙太網路產品有不正常現象,請下載 " How to identify authentic ASIX USB to LAN Products " 文件,先自行確認一下是否正在使用非真正亞信USB轉乙太網路晶片的產品. 如果您買到非真正亞信USB轉乙太網路晶片的產品,請找該產品製造商或經銷商要求相關驅動程式與技術支持.

  我瞭解

 AX78140 -- USB 2.0轉多I/O (4S, 2S+1P) 控制器 New!

With the rapid proliferation of USB interface in the embedded world, developers are looking for easiest ways to add USB to microcontroller-based applications in their design. ASIX’s new AX781x0 family features four USB connectivity bridge solutions including USB 2.0 to Single Serial (AX78120), USB 2.0 to Dual Serial (AX78120), USB 2.0 to Quad Serial (AX78140) and USB 2.0 to Dual Serial and Single Parallel (AX78140) controllers. Enabling smooth migration from legacy system using ASIX’s MCS78x0 series, AX78120/AX78140 provide pin-to-pin compatible and driver backward compatible with MCS7810/MCS7820/MCS7840.

AX78140 is a USB 2.0 to Multi I/O (4S, 2S+1P) Controller. It has been developed to connect a wide range of standard serial devices to a USB host.

The AX78140’s support for the following serial communication program are included: HyperTerminal, PComm, Windows direct connection, Windows dial-up connection through modem, Networking over IrDA and Windows direct connection over IrDA, Minicom.

The AX78140, in 64-pin LQFP, are available with RoHS compliant package and supports commercial grade operating temperature range from 0 to 70°C and industrial grade from -40 to 85°C.
