描述 Description

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.
