General Description
Ordering Information
The Nm9820 is a PCI based single-channel high
performance UART. The Nm9820 offers 16 byte
transmit and receive FIFO compatible with standard
16C550. The Nm9820 perform serial-to-parallel
conversions on data received from a peripheral device,
and parallel-to-serial conversion on data received from
its CPU.
Commercial Grade
Nm9820CV 128-VQFP 0° C to +70° C
Industrial Grade
Nm9820EV 128-VQFP -40° C to +85° C
The Nm9820 is ideally suited for PC applications, such
as high-speed COM ports. The Nm9820 is available in
128-Pin QFP package, it is fabricated in an advanced
in submicron CMOS process to achieve low drain power
and high-speed requirements.
