General Description
The MCS9820 is a PCI based single-channel high performance
UART. The MCS9820 offers 16-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.
