MCS9820
The MCS9820 is a PCI based single-channel high performance UART. The MCS9820 offers 32-byte transmit and receive FIFO compatible with standard 16C550. The MCS9820 performs serial-to-parallel conversions on data received from a peripheral device, and parallel-to-serial conversions on data received from its CPU.
The MCS9820 is ideally suited for PC applications, such as high-speed COM ports. The MCS9820 is available in a 128-pin QFP package. It is fabricated using an advanced submicron CMOS process to achieve low drain power and high-speed requirements.
