亚信电子提醒您  
亲爱的客户您好:

假如在使用亚信USB 转以太网路产品有不正常的现象,请下载 " How to identify authentic ASIX USB to LAN Products " 文件,先自行确认一下是否正在使用非真正亚信USB转以太网路芯片的产品。如果您买到非真正亚信USB转以太网路芯片的产品,请找该产品制造商或经销商要求相关驱动程序与技术支持。

  我了解

 MCS9845 -- PCI转双串口和ISA控制器

The MCS9845CV-BA is a PCI based single function I/O Adapter. It has two 16C450/16C550 compatible UART channels and ISA style interface to add external UARTS and Parallel Ports.

The MCS9845CV-BA has 32-Byte transmit and receive FIFO for each UART channel. MCS8935CV-BA performs serial-to-parallel conversions on data received from a Serial device, and parallel-to-serial conversions on data received from its CPU.

ISA Style interface is designed to add additional Serial / Parallel Ports by using external ISA peripherals. ISA interface can be used for Serial / Parallel port expansion through ISA : 4 Serial or 2 Serial + 1 Parallel.

The MCS9845CV-BA is ideally suited for PC applications, such as Add-On COM ports and Parallel Ports. It is available in 128-Pin QFP package & fabricated using an advanced submicron CMOS process to achieve low power drain and high-speed requirements.

MCS9845CV-BA is designed to be pin compatible with previous version of MCS9845CV. Existing designs of MCS9845 can be migrated to MCS9845CV-BA without any modification to system design. Software compatibility is also maintained between MCS9845, MCS9845CV-BA.
