MCS9820 -- PCI转单串口控制器
|The MCS9820CV-BA is a PCI based single function I/O Adapter. It has one 16C450/16C550 compatible UART.
The MCS9820CV-BA has 32-Byte transmit and receive FIFO for UART channel. MCS9820CV-BA performs serial-to-parallel conversions on data received from a Serial device, and parallel-to-serial conversions on data received from its CPU.
The MCS9820CV-BA is ideally suited for PC applications, such as Add-On COM 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.
MCS9820CV-BA is designed to be pin compatible with previous version of MCS9820CV. Existing designs of MCS9820CV can be migrated to MCS9820CV-BA without any modification to system design. Software compatibility is also maintained between MCS9820CV to MCS9820CV-BA.
